Am Noise Filter
- Noise reduction is the process of removing noise from a signal. Noise reduction techniques are conceptually very similar regardless of the signal being processed, however a priori knowledge of the characteristics of an expected signal can mean the implementations of these techniques vary greatly
- (Noise Filtering) Cleaning the signal (AC) from any interference.
Advanced Digital Signal Processing and Noise Reduction
Digital signal processing plays a central role in the development of modern communication and information processing systems. The theory and application of signal processing is concerned with the identification, modelling and utilisation of patterns and structures in a signal process. The observation signals are often distorted, incomplete and noisy and therefore noise reduction, the removal of channel distortion, and replacement of lost samples are important parts of a signal processing system.
The fourth edition of Advanced Digital Signal Processing and Noise Reduction updates and extends the chapters in the previous edition and includes two new chapters on MIMO systems, Correlation and Eigen analysis and independent component analysis. The wide range of topics covered in this book include Wiener filters, echo cancellation, channel equalisation, spectral estimation, detection and removal of impulsive and transient noise, interpolation of missing data segments, speech enhancement and noise/interference in mobile communication environments. This book provides a coherent and structured presentation of the theory and applications of statistical signal processing and noise reduction methods.
Two new chapters on MIMO systems, correlation and Eigen analysis and independent component analysis
Comprehensive coverage of advanced digital signal processing and noise reduction methods for communication and information processing systems
Examples and applications in signal and information extraction from noisy data
Comprehensive but accessible coverage of signal processing theory including probability models, Bayesian inference, hidden Markov models, adaptive filters and Linear prediction models
Advanced Digital Signal Processing and Noise Reduction is an invaluable text for postgraduates, senior undergraduates and researchers in the fields of digital signal processing, telecommunications and statistical data analysis. It will also be of interest to professional engineers in telecommunications and audio and signal processing industries and network planners and implementers in mobile and wireless communication communities.
Marantz 2130 Tuner
This is one of the finest FM tuners I have ever had the pleasure of using; easily on a par with the best from Macintosh, Sansui and others I've owned. Produced during the late 1970's, the 2130 was the penultimate result of a specifications and fidelity war in the consumer tuner and receiver market. Marantz pretty much pulled out all the stops for this one, and you can hear it if you have a good FM station to listen to. Personally, I pipe either a CD changer or Sirius satellite radio down some 75 ohm coax and have it hooked into every FM receiver in my home; keeps me from having to listen to the farm report and the other things my community (apparently) wants the local FM station to play. The compression on satellite radio doesn't result in extremely high fidelity, but if the choice has to be tolerable music at moderate fidelity, and high fidelity dreck... I'll take the moderate fidelity every time. At least I can count on the 2130 getting the best reproduction of the audio I have available to me. :)
The oscilloscope on the left can display tuning (center and strength at the same time), multipath, and audio. In audio mode, the left and right channels drive the horizontal and vertical signals respectively, so a mono signal draws a 45 degree line and stereo signals draw various elliptical patterns. It's quite informative, you can see how much separation there is at any one moment, and any noise comes through as fuzz on the trace. For multipath, the scope makes antenna adjustment (beam FM antennas) 100% accurate, you can tell instantly when you've got the antenna pointed in the optimum direction. The scope also has external inputs so you can monitor audio from the rest of your stereo system. On the front, there are horizontal and vertical positioning controls and an external level adjust. On the rear deck are focus and brightness adjustments; I've never had to touch them.
Aside from the scope and its controls, the tuner provides controls for two IF bandwidths, switchable AFC ("Quartz Lock"), mono/stereo, muting level and output level, 400 Hz calibration tone for Dolby recording, high blend (multiplex noise filter) and switchable Dolby demodulation (the latter being useless to most people now, as no station uses this anymore... but I just happen to have a low-power ultra-hifi Dolby FM transmitter... :-)
The AFC switches off when you have your hand on the dial, so you can tune normally. It feels silky smooth, and the tuner's ability to separate stations makes tuning quite crisp when you're on-station. As soon as you take your fingers off the knob, the AFC locks back in (if you have it on, of course) and the scope shows the station perfectly centered. The lock LED shows that the AFC is operating.
The AM side of the tuner is pretty good, but not up to the standards of the FM side. Too bad; it's not all that difficult to make a good AM tuner, but very few manufacturers ever paid proper attention to the problem in a consumer audio context. One notable exception to that being Sanyo. Not that it matters anymore; quality AM broadcasting, sad to say, is dying. The airwaves are filled with talking heads. Babbling heads. Something like that.
From time to time, you can find 2130 tuners for sale on EBay. My advice is, if you like FM listening, grab one. They're incredibly underpriced. They generally go for $500 to $750, depending on condition; but you can't buy a comparably performing tuner today for under five grand, and even then, you won't get some of the amenities you get with one of these. No kidding. If you like FM, this baby is the brass ring.
Test shots indoor, low-light, art filter: B&W Grainy
Shot in JPEG. Adobe camera RAW support for E-P3 just came out, but I haven't tried it, yet.
The E-P3 with 12mm f/2 lens performs well in low light—BUT, at ISO1600, I noticed much loss in details the shadow areas, not to mention presence ugly color noise. Now, that was with default settings—noise reduction ON, and "Noise Filter" standard.
For this image, I had Noise Filter off, but forgot to turn off Noise Reduction. By the way, the default menu system hides the user from tweaking with noise settings. I had to look at the instruction booklet to figure out how to turn off NR.
I am pretty impressed with the B&W grainy filter. In low-light, it does a great job, processing the images that actually look like they were shot with something like Ilford Delta 3200 film. IMO, the in-camera processor for grainy B&W does better than film simulation from Silver Efex (v1,at least).
There are (2) types of grainy B&W—(I) high contrast, (II) lower contrast (I think). I don't remember which one this image is, but I think it's (II).

Red Bull Air Race 092 Car Queue
After queueing for an hour to walk out, we queued for over 2 hours to drive out of the field. There was no marshalling so it was a free for all. Everyone just pointed their cars at the exit and hoped for the best. Most were pretty good and filtered considerately (with one noteable exception!). When we got to the gate there was one poor girl sending cars through one at a time.
If they'd had four or five proper queues it would have been quicker because she could have let, say, five cars from each queue go through at a time. Very badly organised.
Engine Air Filter
Wendy was helping me work on the car and she noticed that the engine
air intake was totally loose and pretty much disconnected. We clamped
it down and hoped for the best.

Recovering From Heart Surgery DVD (For Heart Bypass, Heart Valve Surgery and other Open Heart Surgery Patients)
Whether it's a bypass or a valve repair or replacement, heart surgery of any kind is a very frightening experience for both patients and their famililes. It is often overwhelming and difficult to clearly understand and remember discharge instructions and what to expect when you get home. The goal of this 28-minute video is to walk you through some important steps of heart surgery recovery and help you have a more informed post surgical experience. During the initial 4-6 weeks after surgery, it is important to establish a daily routine and to fully understand the restrictions and guidelines provided to you by your healthcare team. This video is divided into chapters and designed to help you with a number of specific activities, including how to get out of bed, and how to perform your deep breathing exercises. The video also offers tips about taking your medication, inspecting your incisions, exercise and much more. RecoverRite® was founded on the premise that knowledge is power, and that patients and family members need specific tools to help them better understand and manage recovery and expectations of life after heart surgery. Every heart surgery is unique and each person will heal differently so be sure to discuss the contents of this DVD with your doctor.

Moto PEBL - INFRARED
So i was excited to visit Angel Island and take some nice infrared photos. It was going to be a fun day. Once i got to the island, i realized that i had my infrared camera but had left my memory cards at home. I was SO bummed. I did have my girlfriends camera with me to take some shots on the island, but no infrared. I tried putting the HOYA 72 filter up to my cell phone and WOW! it took infrared pics. Not good quality, but a fun little experiment. Who knew.
I bought an infrared flashlight a few weeks ago. It's a little known fact that cheap digital cameras (like the kind they put in cell phones) are sensitive to infrared. (Fancier digital cameras have an IR filter.)
This is a photo of a coffee package taken in normal light and infrared.
