Frequency Changing and Tracking in Receivers: The mixer is a nonlinear device having two sets of input terminals and one set of output terminals. The signal from the antenna or…
Theory of Frequency Modulation and Phase Modulation: Frequency Modulation and Phase Modulation is a system in which the amplitude of the modulated carrier is kept constant, while its frequency and…
Solid State Relay Interfacing: To avoid the problems of mechanical relays, Solid State Relay Interfacing are used. In this triac is used as a switching element and isolation is provided…
Basic Aspects of Control System Design of Microprocessor Based Variable Speed Drives: Based on the examples of drives discussed in the foregoing, general outlines may be drawn for designing the…
Nodal Analysis Examples: Nodal Analysis Examples - we discussed simple circuits containing only two nodes, including the reference node. In general, in a N node circuit, one of the nodes…
Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…
Generator Transformer Protection: Generator Transformer Protection - Protective relays, being component parts of electrical switchgear, should be closely associated with the control section of such systems, e.g. indicating and signalling systems. Thus the signalling and indicating systems…
Network Terminology: In this Network Terminology, we shall define some of the basic terms which are commonly associated with a network. 1.Network Any arrangement of the various electrical energy sources…
