Web(The FIR design method used involves sampling the IIR filter impulse response and applying DC correction.) Here the FIR filters needs to be ~40 taps or longer to begin to accurately approximate the IIR filters. The 10, 20 and 30 tap FIR filters have significant ripple and deviate from the IIR, in magnitude, by up to ~6 dB. WebMay 14, 2015 · I am designing an IIR 2nd order Lowpass filter with sampling frequency = 100Hz and cutoff frequency = 10 Hz. The filter coefficients are of Chebyshev Type I using fdatool in Matlab. But the code is not able to filter the signal (i.e. for all frequencies it gives the output with same amplitudes as the input signal) .
