Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
Monochrome Television Receiver Block Diagram: Monochrome Television Receiver Block Diagram as shown in Figure 17-9, TV receivers use the superheterodyne principle. There is extensive pulse circuitry, to ensure that the…
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…
Ruby Maser: As was know ferrites of certain materials have atomic systems that can be made to resonate magnetically at frequencies dependent on the atomic structure of the material and…
Gunn Effect: In 1963, Gunn discovered the transferred electron effect which now bears his name. This Gunn Effect is instrumental in the generation of microwave oscillations in bulk semiconÂductor materials.…
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…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the…
