Transistor Detector Circuit Working Principle: It is possible to achieve amplitude demodulation by using a three-element electronic device. A typical example of such a configuration is illustrated in Fig. 22.51.…
Linear Diode Detector or Envelope Detector: Diode detection is called the envelope detection as it recovers the audio frequency signal envelope from the composite signal. Diode detector is also called…
Photodetectors - Definition and Applications: Photodetectors are the semiconductor devices that can detect optical signals through electronic processes. The extension of coherent and incoherent light sources into the far-infrared region…
Phototransistor Construction and Working Principle: The sensitivity of a photo diode can be increased by as much as 100 times by adding a junction, resulting in an NPN device. A…
Waveguide Mixers and Detectors: As we know that ordinary transistor and tube RF amplifiers eventually fail at microwave frequencies, because of greatly increased noise, compared with their low-frequency performance. Unless…
Speed Detector: One important factor in the closed loop control of variable speed drives emÂploying solid state converters is the Speed Detector. In the dedicated hardware control using analog components,…
Level Detector: Schmitt trigger or level detector circuits are very often employed in static relay circuits as a final stage before the trip coil circuit of the circuit breaker. The…
Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…
