Coupled Circuits Definition: Two circuits are said to be 'coupled' when energy transfer takes place from one circuit to the other when one of the circuits is energized. There are…
Two Port Network Articles: Terminal Pairs or Ports: A pair of terminals at which an electrical signal may enter or leave a network is called a port. The terminals or…
h Parameters of Two Port Network: h Parameters of Two Port Network are also called hybrid parameters. These parameters are very useful in constructing models for transistors. The transistor parameters…
Basic Components of Static Relays Articles Semiconductor Diodes in Static Relays: The pn junction has rectifying characteristics as shown in Fig. (10.1). If a source of emf is connected to…
Basic Elements of Static Relay: The basic elements of a static relay are namely, Input Element: Mixing circuits are needed to sum the input signals in a convenient form. Semiconductor…
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…
