Compare the outputs of the partitioned filter and the original filter. Design the FIR lowpass filter coefficients using the fir1 function. The sampling frequency is 8 kHz and the cutoff frequency of the filter is 2 kHz. The impulse response is of length 4000. WitrynaYou need to evaluate H ( z) on the unit circle z = e i w in order to get the frequency response (assuming that the system is stable, i.e. the region of convergence contains the unit circle). But your Z -transform looks a bit unusual because for causal signals (or filter impulse responses) you should get negative powers of z: solderless press-fit pin headers
