Consider the bandpass signal x(t) whose complex envelope is equal to x(t) = x(t)+jxo(f). Derive an expression for the autocorrelation function and the power spectrum density for x(t) and x(t). Assume that the signal x(t) is the input to an LTI filter whose impulse response is h(t); give an expression for the output's autocorrelation and power spectrum density.
