The transistor reactance modulator shown in the Figure is to be used in an FM transmitter. The input resistance of the transistor is 600 Ω and beta transistor is 65. (a) How much capacitance does this ...

The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also relatively straightforward to ...

In 2004, electrical engineering pioneers Nick Holonyak, Jr. and Milton Feng at the University of Illinois invented the transistor laser--a three-port device that incorporated quantum-wells in the base ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
