Microwave Link in Electronic Communication: A Microwave Link in Electronic Communication performs the same functions as a copper or optic fiber cable, but in a different manner, by using point-to-point…
Multiplexing in Electronic Communication: Multiplexing in Electronic Communication is the sending of a number of separate signals together, over the same cable or bearer, simultaneously and without interference. There are…
Network Protocols in Digital Communication: "Intelligent" (microprocessor-controlled) switching systems have become the hubs of intelligent networks. Terminal devices and line connection equipment have also been given microprocessor "brains," and thus…
Switching Systems in Digital Communication: If only two sites are to be connected, switching is not required. The two facilities are interconnected on a point-to-point basis. However, switching is likely…
Measurement of Information in Communication System: Having said what information is not (it is not meaning), we now state specifically what information is. Accordingly, information is defined as the choice…
Tunnel Diode Applications: In all its Tunnel Diode Applications, the tunnel diode should be loosely coupled to its tuned circuit. With lumped components, this is done by means of a…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the…
