WebThe great majority of audio filters are LTI, for several reasons: First, no new spectral components are introduced by LTI filters. Time- varying filters, on the other hand, can generate audible sideband images of the frequencies present in the input signal (when the filter changes at audio rates). WebThe response of a continuous-time LTI system can be computed by convolution of the impulse response of the system with the input signal, using a convolution integral, … Web(a) If h (t) is the impulse response of an LTI system and h (t) is periodic and nonzero, the system is unstable. (b) THe inverse of a casual LTI system is always casual. (c) if h [n] ≤K for each n, where K is a given number, then the LTI system with h [n] as its impulse response is stable. chef ian haste
