I tried to use FIR Filter Block(coefficients calculated by MATLAB) in ADAU1701 and ADAU1452. But I get different results. ADAU1452 provides a linear phase FIR filter, but I don't want it.
I guess FIRSigma300Alg and FIRFiltAlg are quite different. FIRSigma300Alg has an unknown treatment on phase response.
So how can I use FIR Filter Block like ADAU1701(FIRFiltAlg) in ADAU1452 board? I want a clear FIR filter with no other treatment in ADAU1452 board.
