8.3 by using the form of the channel de ned in equation (8.46), plot a hundred random qpsk constellation points and the magnitude squared of the fft (and use zero-padding to smooth the shape) of the channel for a single draw for a given channel de ned by (a) no delay spread, (b) k = 0: 3, (c) k = 1, (d) k = 3, (e) k = 10, (f) k = 25.

On a average work day more than work place firs are reorted

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
