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…
Transistor RF Amplifier Circuit: A radio receiver always has an RF section, which is a tunable circuit connected to the antenna terminals. It is there to select the wanted frequency…
Parameter Passing Techniques in Microprocessor: Parameter Passing Techniques in Microprocessor - Whenever we need to use a group of instructions several times throughout a program there are two ways we…
Types of Circuit Breaker Articles: Air Blast Circuit Breaker Diagram : These breakers employ a high pressure air-blast as an arc quenching medium. The contacts are opened in a flow…
Linear Integrated Circuits Articles: Linear integrated circuits and applications | Op Amp Basics: Linear integrated circuits and applications – The term IC means integrated circuit where all the components are…
