SCR as Half Wave Rectifier Circuit Diagram: SCRs are very useful in ac circuits where they may serve as rectifiers whose output current can be controlled by controlling the gate…
Radio Communication System - Block Diagram and types: Radio communication is very popular technique of communicating a message. The radio waves are electromagnetic waves produced due to escape of electrical…
Square Law Detector Circuit and Working Principle: The square law detector circuit is used for demodulating moduÂlated signal of small amplitude (i.e., below 1 V) so that the operÂating region…
Amplitude Detection Process: Amplitude Detection - The process of demodulation demands that the modulated wave has some definite average value and the carrier wave is separated out. Hence in demodulation…
Single Sideband Modulation (SSB): Single Sideband Modulation (SSB) can he obtained by passing the output of a carrier suppressor (product modulator) through filter circuits that are selective to transmit one…
Generation of DSBSC Signal using Balanced and Ring Modulator: DSBSC signal can be obtained by simply multiplying the modulating signal with the carrier signal. By simple multiplication of Vc sin ωct…
Square Law Diode Modulator - Circuit Diagram and its V-I Characteristics: Basic circuit of a square law diode modulator is shown in Fig. 22.30. It utilizes the nonlinear region of…
Types of Amplitude Modulation (AM): As we know already that, one carrier and two sidebands are produced in AM generation. However, it is not essential that all these signals are…
