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…
Class B Push Pull Amplifier - Circuit Diagram, Operation and Derivation: The circuitry for the Class B Push Pull Amplifier operation is the same as that for the class A…
Class A Push Pull Amplifier - Working Principle, Advantages & Disadvantages: A Class A Push Pull Amplifier circuit is shown in Fig. 17.25. By Class A Push Pull Amplifier means…
What is Low Frequency Compensation? The coupling or blocking capacitor tilts the amplifier response for step input. In Fig. 16.28, if a high value of resistance Rd is added in…
RC Coupled Transistor Amplifier - Operations, Derivation and Applications: A two-stage RC Coupled Transistor Amplifier using N-P-N transistors in CE configuration is shown in Fig. 16.12. The two transistors used are…
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.…
Frequency Stability of Oscillator: An oscillator having initially been set at a particular frequency does not maintain its initial frequency, but instead drift and wander about in frequency, sometimes uniformly…
