Limitations:
1. Silicon transistors do not function at voltages much higher than about 1,000 volts (SiC devices can be worked as high as 3,000 volts). In difference, electron tubes have been developed which can be operated at tens of thousands of volts.
2. High power, high frequency operation, like which employed in over-the-air television broadcasting, is better acquired in electron tubes because of enhanced electron mobility in a vacuum.
3. Silicon transistors are more vulnerable than as compared to electron tubes to an electromagnetic pulse produced by a high-altitude nuclear explosion.
Referring to Figure, let boxes 2, 3, and 5 consist of a 0.2-H inductor, a 5- resistor, and a 0.1-F capacitor, respectively. Given A = 5, and v 1 = 10 sin 10t, i 2 = 5 sin 10t ,

Q. What is power gain? Power gain is the ratio of power delivered to the load to power delivered to the amplifier is the power gain. A p =P o /P i =V o I o /V i I s
Q. The loop gain of an elementary feedback control system(see Figure) is given by G(s)·H(s), which is 10/(1+s/2)(1+s/6)(1+s/50). Sketch the asymptotic Bode plot of the loop-gain fu
