Post by thread:[EE]: Active Noise Cancellation

To all: Can anyone direct me to websites dealing with active noise reduction, or toward information on phase inverting audio amplifiers?

Try the International Conference on Signal Processing Appliacations and Theory website at http://www.icspat.com . They have an archive of papers from the last few years including a fair few on Noise cancelllation. From brief forays into this before I know that LMS is one of the more cpommonly used algorithms, and many of the papers only mention LMS not ANC so have a look at them too. In particular I found the "Implementation of Delayed Normalized LMS Algorithm on the TMS320C50 Digital Signal Processor" paper to have quite good coverage from basic principles to algorithm implementation.
