Electrostatic Precipitator (ESP) - Construction and Working Principle: Electrostatic Precipitator is located between the boiler and the chimney, it extracts the fly ash from the flue gases and thus prevents…
Commutating Capacitor in Bistable Multivibrator or Speed up Capacitor: Commutating Capacitor in Bistable Multivibrator is also called as Speed up Capacitor. Whenever a triggering pulse is applied to change the…
Bistable Multivibrator - Working and Types: A bistable multivibrator, as its name implies, has two stable states. It can stay in either of the two states indefinitely (as long as…
Monostable Multivibrator - Operation, Types and Application: Monostable multivibrator is a two-stage amplifier with two states—one stable state and another quasi-stable state. The circuit has two transistors Q1 and Q2,…
Astable Multivibrator Definition and its Working: The multivibrator circuit which has no stable state is called the astable multivibrator. The two states of operation of astable multivibrators are quasi-stable (temporary)…
Step up Chopper - Definition, Circuit Diagram and its Working Principle: In a step-down chopper the output voltage lies between zero and supply voltage. However, there are techniques by which…
Emitter Modulation - Circuit Diagram and its Operation: The circuit for emitter modulation is shown in Fig. 22.29. It is essentially a CE amplifier. The carrier signal from a crystal…
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…
