An FIR filter is designed by finding the coefficients and filter order that meet certain specifications, which can be in the time domain (e.g. a matched filter) and/or the frequency domain (most common). Matched filters perform a cross-correlation between the input signal and a known pulse shape. The FIR convolution is a cross-correlation between the input signal and a time-reversed copy of the impulse response. Therefore, the matched filter's impulse response is "designed" b… WebJan 26, 2014 · LMS Filtered Speech Signals of Echo Cancellation using µ = 0.1, 0.01 í µí± í µí± í µí± 0.001: N=10 taps …
