Broadband Communications Systems Articles: 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…
Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite…
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…
Coaxial Cable in Communication System: A Coaxial Cable in Communication System consists of a tube carrying a number of coaxial cables of the type, together with repeaters and other ancillary…
Telegraphy in Electronic Communications: Telegraphy in Electronic Communications that employs typewriter like machines operating at a maximum speed of about 60 words per minute (wpm) to send written messages from…
Semiconductor Microwave Devices Articles: Trapatt Diode Construction and Working: The Trapatt Diode Construction and Working is derived from and closely related to the IMPATT diode. Indeed, as pointed out near…
Semiconductor Lasers: Semiconductor Lasers was discovered in 1962 that a gallium arsenide diode, such as the one shown in Figure 12-41, is capable of producing laser action. This occurs when…
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…
