Function Generator Block Diagram: A Function Generator Block Diagram produces different waveforms of adjustable frequency. The common output waveforms are the sine, square, triangular and sawtooth waves. The frequency may be adjusted, from a fraction…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists a definite nonÂlinear relationship between…
Fully Automatic Digital Instrument: Fully Automatic Digital Instrument - A multimeter with automatic polarity indication, automatic zero correction and automatic ranging (of course coupled with automatic decimal point indication) only needs a signal applied to…
Full Wave Rectifier DC Power Supply: Like half-wave rectifiers, full-wave rectifiers require filter circuits to convert the output waveform to direct voltage. Figure 3-13 shows a Full Wave Rectifier DC Power Supply with a reservior…
Fuel Handling System and Ash Handling System: Handling of coal: The coal handling is divided into two types: Out-plant handling. In-plant handling. 1. Out-plant handling: This handling includes the handling of coal from coal mine…
Fuel Cell Working Principle and Schematic Diagram: Fuel Cell Working Principle explains that it is an electrochemical device that converts chemical energy of a conventional fuel directly into low voltage D.C. electrical energy. It is…
Friction Interview Questions and Answers: 1. Define the term 'Friction'. Ans. If two bodies are in contact with one another. The force exerted between them at their point of contact to prevent one body from…
Frequency Translator using PLL: The Frequency Translator means shifting the frequency of an oscillator by a small factor. Fig. 2.134 shows the block schematic for frequency translator using PLL. It consists of mixer, low pass…
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 in one direction, sometimes quite…
Frequency Shift Keying Demodulator Working (FSK): In digital data communication, binary data is transmitted by means of a carrier frequency. It uses two different carrier frequencies for logic 1 and logic 0 states of binary…
