. The received signals can be modeled by x(t)=s(t)+w(t), where s(t) is the desirable signals modeled by a zero-mean Gaussian random process with a Gaussian power spectrum density (PSD) of S, (f) = e 2² and w(t) is the additive white Gaussian noise (AWGN) with zero-mean and average power of Pn. Additionally, s(t) and w(t) are WSS and uncorrelated. (a) Find the autocorrelation function of x(t), (b) find the PSD of x(t), (c) plot both ACF and PSD of x(t) and properly label your plot to indicate Ps, P. and σ. νεπσ
