TV Receiver Synchronizing Circuits: The task of the TV Receiver Synchronizing Circuits is to process received information, in such a way as to ensure that the vertical and horizontal oscillators…
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…
Characteristics of Data Transmission Circuits: Bandwidth Requirements - Characteristics of Data Transmission Circuits is the most instances consists of pulse-type energy. The data stream is similar to a square-wave signal…
Microwave Tubes and Circuits Articles: Triode Equivalent Circuit: As frequency is raised, vacuum tubes suffer from two general kinds of problems. The first is concerned with interelectrode capacitances and inductances,…
Triode Equivalent Circuit: Triode Equivalent Circuit - As frequency is raised, vacuum tubes suffer from two general kinds of problems. The first is concerned with interelectrode capacitances and inductances, and…
Waveguide Isolator and Circulators: It often happens at microwave frequencies that coupling must be strictly a one-way affair. This applies for most microwave generators, whose output amplitude and frequency could…
Ratio Detector Circuit: In the Foster-Seeley discriminator, changes in the magnitude of the input signal will give rise to amplitude changes in the resulting output voltage. This makes prior limiting…
Squelch Circuit: Squelch (muting):Â When no carrier is present at the input, i.e., in the absence of transmissions on a given channel or between stations, a sensitive receiver will produce a…
