Develop a set of performance curves, similar to those shown in Figure 7.8, that illustrate the performance of a coherent demodulator as a function of the phase-error variance. Let the SNR be a parameter and express the SNR in decibels. As in Figure 7.8, assume a QDSB system. Repeat this exercise for a DSB system.
Find the rpm of the motor if it is lifting a 4-oz load by a string over a 3-in. radius pulley.
The number of turns in primary and secondary of an ideal transformer are N1 = 50 turns and N2 = 400 turns. The primary winding is connected to a 120 - V, 60 Hz source with a source resistance of 50 Ω. The secondary winding is connected to a 1600 ..
