A 250hp, 500v dc shunt motor draws a nominal field current of 5A under rated load. The resistance is 90ohms. Calculate the ohmic value and power of the series resistor needed so that the field current drops to 4.5A
Describe the performance differences between an AM and FM system. Be sure toinclude parameters suchas: Power efficiency, spectral efficiency,noise immunity,and performance.
3) If the input voltage to a Full-Wave Bridge Peak Rectifier is vi(t) = 10.4sin(600t) Volts, what is the peak output voltage. Assume all diodes have a 0.7V drop, (ie. VD = 0.7V). 4) For the previous problem, if the resistor in the circuit is equal t..
Describe why the intrinsic carrier concentration changes with temperature. This would include from very cold temperatures to 600K+ temperatures. Why does an extrinsic semiconductor become intrinsic above ~ 500K
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
