Let X ( t ) and Y ( t ) be two real, independent, widesense stationary random processes deﬁned on a random experiment. Let Z ( t ) be a new random process deﬁned as Z ( t ) = X ( t ) Y ( t ) . Under what conditions is Z ( t ) WSS? – 1 – 15. Let X ( t ) is given by X ( t ) = cos ( ω o t +Θ) , where Θ is a random variable uniformly distributed on the interval [0 , 2 π ) and Y ( t ) is a widesense stationary random process with autocorrelation function R Y ( τ ) = eα  τ  , where α is a positive constant. Assume X ( t ) and Y ( t ) are statistically independent. Let Z ( t ) = X ( t ) Y ( t ) . Find the power spectral density of Z ( t ). – 2 –...
