WebDescription. h = firminphase (b) computes the minimum-phase FIR spectral factor h of a linear-phase FIR filter b. You can find the maximum-phase spectral factor, g, by reversing h such that g = fliplr ( h ), and b = conv (h, g). example. h = firminphase (b,nz) specifies the number of zeros, nz, of b that lie on the unit circle.
