WebOct 7, 2024 · 1 Answer. There's a ROC (region of convergence) problem in your derivation. Consider a decomposition of the signal as x [ n] = x 1 [ n] + x 2 [ n]. Then in order for the Z transform of x [ n] to exist, the corresponding Z -transforms of both x 1 [ n] and x 2 [ n] must exist for a set of z which is the intersection of the individual ROCs of the ...

WebOct 12, 2015 · Now the problem is that this phase plot is wrong, the DTFT is the sum of real sinc functions so its phase spectrum con only assume k*pi values. There's still a linear component in the phase plot and the slope is positive so the exponentials that I'm using are over compensanting the delay. WebThe transfer function of an analog lter is given by the Laplace transform of its impulse response, H a(s) = Lfh(t)g:= Z 1 1 h(t)e stdt: (22) The subscript ais used to denote an analog transfer function. For realizable analog lters, the transfer function can be written as a rational function, H a(s) = P(s) Q(s) (23) where P(s) and Q(s) are ...
