Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
Sampling Circuits: Sampling Circuits is one which allows a comparison of instantaneous values derived at different instants of time, thereby dispensing with the need to phase shift and mix signals…
Square Wave Generators: Diode clippers can be used to remove the curved portion of the sinusoidal wave to give square waves. The operational amplifier together with an integrator, can be…
Smoothing Circuits: The rectified a.c. consists of a series of undirectional half waves of current or voltage. It is generally desirable to smooth this output. The various filters used for…
Logic Circuit in Static Relay: The concept of Logic Circuit in Static Relay can be better understood by considering the logic operations performed by the devices rather than the actual…
Thyristor in Static Relay: The structure of Thyristor in Static Relay consists of four alternate p-and n-type layers. In the thyristor (also called a silicon controlled rectifier—SCR) connections are made…
Hall Effect Relay Circuit: Hall Effect Relay Circuit is utilized to give a phase comparator. The effect is very predominant in certain semiconductors such as indium arsenide, indium antimonide, indium…
Static Relays Basics and Classification: A Static Relays Basics refers to a relay in which the measurement or comparison of electrical quantities is done in a static network which is…
