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.
Kirchoff's Current Law The total current entering a node in a circuit is equal to the total current leaving that node. A Node is a junction between two or more components.
what is emitter efficiency
A sequential circuit has two inputs w1 and w2, and an output, z. Its function is to compare the input sequences on the two inputs. If w1=w2 during any four consecutive clock cycl
