For each of the following, determine whether the random process is (1) WSS or (2) mean square ergodic in the mean. a. () = A, where A is a random variable uniformly distributed between 0 and 1.(5pts)b. ()=0, where A is a Gaussian random variable with mean 0 and variance 1.(5pts)c. ()=0+(0) where A, B are uncorrelated zero-mean random variable with variance 2.(5pts)

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
