Photoconductive Cell Construction and Working: Photoconductive Cell Construction and Working - Light striking the surface of a material can provide sufficient energy to cause electrons within the material to break…
Decibels and Half Power Point Method: Power Measurement in Decibels and Half Power Point Method - The power gain (Ap) of an amplifier may be expressed in terms of the…
Noise in Information - Carrying Channel: Noise in Information-carrying capacity of a channel. This idea will now be explored further, as will means of combating noise. Effects of Noise: That…
Electromagnetic Spectrum: In an earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself; some of this…
Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator,…
Audio Frequency Transformer: Audio Frequency Transformer is used at the output stage of Audio Frequency electronic amplifier for matching the load to the output impedance of the power amplifier stage.…
Variable Frequency Transformer | Application: So far we have considered transformers which operate at fixed frequency (50 Hz). Their purpose is to transform electric power from one voltage level to…
