@Giulia Lattanzi — The way I generally determine them it is to take the fft of the transfer function and then plot only the imaginary part as a function of frequency. The poles (and their frequencies) as well as the zeros (and their frequencies) should readily reveal themselves. Be sure to note whether there are any of either at zero or infinity.transfer function and 'causal' signal - evaluate transfer function or use z-transform of input? 1.
