Define Suppression of Carrier: Three main systems are employed for the generation of SSB; the filter method, the phase cancellation method and the "third method." They differ from one another…
Single Sideband: A brief, if not oversimplified, explanation of Single Sideband will help in understanding the transmission process. To begin, we must review some basic transmission processes. The physical length…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Measurement Set Up in Electronic Instrumentation Articles: Microwave Power Measurement Techniques: Microwave Power Measurement Techniques can be done by the use of wavemeters. A wavemeter is an adjustable resonant circuit…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation…
Schering Bridge Theory for Three Terminal Measurement: For two terminal measurements the bridge is grounded at its junction points. The supply transformer, detector, and all the components of the bridge…
