Q. What do you mean by Feedback in amplification?
Feedback : Feedback in its broadest sense means that a certain amount of the output signal is "fed back" into the input. An amplifier - or an element of an amplifying device - is presented with the input signal, and compares it to a "small scale replica" of the output signal.
If there is any difference, the amp corrects this, and ideally ensures that the output is an exact replica of the input, but with a greater amplitude. Feedback may be as a voltage or current, and has a similar effect in either case.
Q. What are the Constructional Features of DC Machines? Adc generator ormotormay have asmany as four fieldwindings, depending on the type and size of the machine and the kind o
Q. A transformer is rated 10 kVA, 220:110 V (rms). Consider it an ideal transformer. (a) Compute the turns ratio and the winding current ratings. (b) If a 2-load resistance
Q. The parameters of a BJT are given by α = 0.98, I CBO = 90 nA, and i C = 7.5 mA. Find β, iB, and iE.
Q. How does a MOSFET amplify electrical signals? While a minimum requirement for amplification of electrical signals is power gain, one finds that a device with both voltage an
Distribution Loss Reduction and Efficiency Improvement You are well aware of the fact in which all energy supplied to a distribution utility does not reach the end consumers.
