How can we compute the magnitude response of a complex equalizer (CE) after convergence ? There is 4 fir filters in a CE ! Thanks Tom

Hello, you could reduce it to a single equivalent filter and determine its |H(f)| if the filters are in series: convolve the coefficients if they are in parallel (unlikely, but I don't know your design): add the coefficients. The result is the equivalent filter as FIR, its coefficients are the impulse response Frequency response => Fourier transform of impulse response Alternatively, send an impulse through your design. Hope that's useful. -Markus
