FET Amplifiers,d. For most usable transducers the output is in the form of electrical energy. Some examples of these transducers are sound detectors or microphones, television cameras, heat detectors, nuclear detectors, strain gauges, solar cells, and other photoelectric devices. The output voltage that is obtaine

Ultrahigh Frequencies,t to look at some of the effects when the frequencies are in the order of 100 megahertz and higher. These get into the ultrahigh frequencies and the microwave range. First, let us discuss some of the properties of dc voltages and currents and then ac as the frequencies increase from the audio range
