Extensions of Single Sideband Amplitude Modulation: The Extensions of Single Sideband Amplitude Modulation is namely, Forms of Amplitude Modulation: This section on amplitude modulation defines, describes and lists the main applications of the various forms of…
Exponential Variation of the Input to the Controller: The linear Exponential Variation of the input to the Controller, discussed in the foregoing section, is too involved to achieve by means of circuits using discrete elements.…
Explain Vapour Compression Refrigeration System: Vapour Compression Refrigeration System is the most important system from the standpoint of commercial and domestic utility and most practical form of refrigeration. The working fluid, known as a refrigerant,…
Explain Vapour Absorption Refrigeration System: The vapour absorption refrigeration system is one of the oldest method of producing refrigerating effect. The refrigerant, commonly used in this system, is ammonia. This system uses heat energy, instead…
Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into the emitter is referred to…
Explain Steady State Conditions in Semiconductor: Explain Steady State Conditions in Semiconductor - When the P-N junction is forward biased, current flows quite freely P to N in a P-N junction, as discussed in Fig.…
Explain Distortion in Amplifier? | Types of Amplifier Distortion: Under ideal conditions, amplified output signal must have exactly the same waveform as the input signal. But in practical amplifiers, this ideal condition is never achieved.…
Explain Conductivity of Metals: Conductivity of Metals - Consider a conductor of length l metres and cross-sectional area A square metres, as shown in Fig. 6.27. Let the number of free electrons available per m3…
Explain Conduction in Intrinsic Semiconductors: Explain Conduction in Intrinsic Semiconductors - As already explained, conduction through a semiconductor is due to two mechanisms viz. drift and diffusion. The movement of charge carriers (electrons and holes)…
Explain Conduction in Gas: Explain Conduction in Gas - The introduction of small amount of gas into the electron evacuated tubes entirely changes the operating characteristics—materially giving in general a greatly diminished voltage drop and…
