SBR123 - 2014-08-22 13:06:00
Hello All, It is mentioned that ideal phase response of a LTI filter is linear. The reason quoted for this is, for such a system, an sinusoidal input would be pass out without any shape distortion ...linear vs constant phase response of LTI system

SBR123 - 2014-08-22 04:16:00
Hello, Assuming that an input to an LTI filter is an exponential function then output y(n) = A*H(omega)*exp(j*omega*n); Now, assume a LTI filter response is such that, H(omega1) = 1 H(ome...LTI Filter
