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…
Data Communication Circuit using Modem: Data Communication Circuit using Modem - The name modem is a contraction of the term MOdulator and DEModulator. As the name implies, both functions are…
Digital Codes Types: Various Digital Codes Types of equipment are used in computer systems to send and receive data: keyboards, video terminals, printers, paper tape punches and readers, paper card…
Digital Electronics Basics: Digital devices are based on Digital Electronics Basics circuits which can represent two states, ON or OFF. The ability to design integrated circuits consisting of thousands of…
Resonators and Waveguides Articles: Rectangular Waveguides: As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly…
Waveguide Switch Design: It is often necessary to prevent microwave power from following a particular path, or to force it to follow another path; as at lower frequencies, the component…
Waveguide Coupling: When waveguide pieces or components are joined together, the Waveguide Coupling is generally by means of some sort of flange. The function of such a flange is to…
Circular Waveguide: It should be noted from the outset that in general terms the behavior of waves in circular waveguide is the same as in rectangular guides. Analysis of behavior:…
