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.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
