Non-periodic and deterministic signals are energy signals whereas periodic and random signals are power signals. Select one: a. False b. True The signal that can be expressed statistically by mean and variance is called: Select one: O a. Deterministic Signal O b. Random Signal O c. Complex Signal O d. Periodic Signal The x(bt) is a compressed version of x(t) if: Select one: a. b greater than 1 b. b between 0 and 1 c. b=1 d. b less than 1 In these systems any time delay in input signal leads to diffrent time delay in the output signal : Select one: O a. Causal systems b. Time invariant systems c. Time varying systems d. Memory less systems
