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…
Difference Between Frequency Modulation and Amplitude Modulation: The Difference Between Frequency Modulation and Amplitude Modulation are discussed below The frequency modulation (FM) has the following advantages over the amplitude modulation…
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…
Classification of Communication: There are two basic classification of communication systems, baseband systems and passband systems. In baseband systems, the signal is transmitted without modifying the frequency content. A simple…
Basic Block Diagram of Communication System: The Basic Block Diagram of Communication System is shown in Fig. 22.1. The essential components of a communication system are information source, input transducer,…
Stagger Tuned Amplifier - Circuit diagram and its Workings: In order to increase bandwidth, double tuned amplifiers are preferred, but their alignment is difficult. A much better overall response can…
Large Signal Tuned Amplifier - Operation and its Equivalent Circuit: Tuned amplifier circuits are for class A operation and their use is limited to applications in which RF signal has…
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…
