WebMar 23, 2024 · One way to avoid this is by designing a Minimum-phase filter. That is an FIR filter whose impulse response is not symmetric – instead, it is designed to minimize group delay by placing higher valued coefficients first along the delay line. This, however, comes at the cost of a non-linear phase response. WebJul 25, 2024 · derive a complete proof of the equivalence: a FIR filter has (an ti)symmetric coefficients if and. only if the phase is linear. It must be emphasized that this brief paper …
