Asignal consists of the periodic alternating sequences., 2,2, 1, 2, 2, 1,2,2, 1, what is the average power of the signal? (5 point) b) a signal x[n] is periodic with period n-4. some selected values of x[n] are x[1] = 5, x[2] x[4] =-1 , x[10] = 8, x[5-5, and x[7] = 3. what is the average signal power?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
