PARALLEL_T_FILTER_WITH_FEEDBACK

Published:2009/7/14 4:00:00 Author:May | From:SeekIC

Single-transistor feedback circuit Q2 reduces high attenuation in passband that severely limits conventional 60-cps T-notch filter, Filter response is down 1 db at 62 cps. Can be used in reproducing stereo tape, where it will salvage signals normally buried far below noise level of original tape recording. -J. Strattan , Feedback Improves Filter, Electronics, 39:18, p 99.
