Digital Satellite Communication - Definition and Advantages: With the developments in digital electronics technology, access techniques and possibility of expanded communication network, digital signaling techniques have been introduced in communication…
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…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
Peak to Peak Detector - Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal.…
Internal Architecture of 8275 CRT Controller: The 8275 programmable CRT controller is a single-chip device that generates all the signals which are used for interfacing a microprocessor system. The main…
Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
Zero Crossing Detector Circuit: Zero Crossing Detector Circuit basically involves the sine to square wave conversion by a level detector circuit followed by a pulse circuit, which consists of one…
