tap gain correcting circuit Explanation: Adaptive equalizer with variable tap coefficient leakage Document: United States Patent 4575857 Abstract: An automatic equalizer comprises a waveform equalizer having a transversal filter connected to receive an input signal having a linear distortion, and having controllable tap gains; and a tap gain correcting means for successively correcting the tap gains of the transversal filter to take from the transversal filter an output signal from which the linear distortion is removed. In order to maintain the good convergency of tap gain correction control and prevent the excessive increase of the residual distortion, the tap gain correcting means is arranged to add a small leak to the correction control of tap gains. The magnitude of this leak is increased or decreased depending upon the sum of absolute values of the differences between the tap gains and their predetermined values to be set when the input signal contains no distortion. -------------------------------------------------- Note added at 1 hr (2006-06-21 16:05:45 GMT) -------------------------------------------------- http://www.its.bldrdoc.gov/table_mountain/1966/chap2.html Reference: http://www.freepatentsonline.com/4575857.html |
