Interference of Electromagnetic Waves: Interference of Electromagnetic Waves occurs when two waves that left one source and travelled by different paths arrive at a point. This happens very often in…
Intermediate Frequency Amplifier: Choice of frequency: The Intermediate Frequency Amplifier (IF) of a receiving system is usually a compromise, since there are reasons why it should be neither low nor…
Properties of Fluid in Fluid Mechanics: The following properties of fluids are of general importance to the study of fluid mechanics. Mass density (ρ) Specific Volume (v) Specific weight (w)…
PLC Hardware Components: 1. PLC Hardware Components - The input and output interface modules consists of an I/0 rack and individual I/O modules. Input interface modules, accept signals from the…
PLC Structure: The PLC Structure mainly consists of a CPU, memory areas, and appropriate circuits to receive input/output data as shown in Fig. 21.22. A PLC can be considered as…
Standing Wave Ratio Measurements: Standing wave are created along the length of a transmission line due to the mismatch between the characteristic impedance Z0 and the terminating impedance of the…
Electromechanical AD Converter: Another area of application in which Electromechanical AD Converter is very important, involves the translation of the angular position of a shaft into digital information. (A very…
Classification of Active Filters: An electric filter is often a frequency selective circuit that passes a specified band of frequencies and blocks or attenuates signals of frequencies outside this band.…
