Suppose the message signal is a series of rectangular pulses m(t) where us is the unit ste function and suppose the carrier frequency is fc Then plot the waveform of the dsb sc am signal m(tO cos(2pift) and derive the fourier transform

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
