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…
What is Thyristor? - Thyristor Family and its Applications Thyristor is the general name given to a family of semiconductor devices having four layers with a control mechanism, although this…
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…
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…
