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

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).

- Fram ("Forward") is a ship that was used in expeditions of the Arctic and Antarctic regions by the Norwegian explorers Fridtjof Nansen, Otto Sverdrup, Oscar Wisting, and Roald Amundsen between 1893 and 1912.
- Fram is an impact crater in Meridiani Planum, on Mars. It was visited by the rover Opportunity (MER-B) on Sol 84, April 24, 2004.
- In the fiction of J. R. R. Tolkien, the Eotheod were a group of Northmen who became the ancestors of the Rohirrim.
A visit to the Fram museum . Basically a building built around a ship . By modern standards the ship is quite small but within its building it appears gigantic.
Famous for being Roald Amundsons ship on his conquest over Scott in being the first explorers to reach the South Pole on the 14th December 1911. It was 35 days before Scott found the Norwegian flag at the South Pole . Scott and his party died on thier return journey .
The Fram is preserved here for all to see. Its a shame we could not do the same for the Terra Nova .
Fram was also used prior to Amundsons adventures by two other notable Norwegian explorers (though not quite so famous) Sverdrup and Nansen ,for whom the ship was initially designed and built .
The ship Fram which was deliberately frozen into the north polar ice cap & traveled with the ice for 3 years before coming out the other side.
