Unformatted text preview: ( ) [ ] ( ) f U f f p F = exp . and time t , amplitude A , and initial phase are deterministic variables. Also, recall that U ( f ) is a unit step function, which is given by ( ) < = . for for 1 f f f U Determine: (a) [4 points] E { x ( t )} (b) [4 points] E { x ( t 1 ) x ( t 2 )} (c) [1 point] Is x ( t ) a wide sense stationary process? Why?...
