The Negative Feedback in Electronics

https://www.electronics-lab.com/article/the-negative-feedback-in-electronics/

Introduction According to Norbert Wiener, the American mathematician and the father of cybernetics, feedback is a method of controlling a system by reinserting the results of its past performance into it. In a feedback system, a signal that is proportional to the output is fed back to the input and combined with the input signal […]

Frequency Response of Amplifiers

https://www.electronics-lab.com/article/frequency-response-amplifiers/

Introduction As such for any electronic circuit, the behavior of amplifiers is affected by the frequency of the signal on their input terminal. This characteristic is known as the frequency response. Frequency response is one of the most important property of amplifiers. In the frequency range that amplifiers have been designed for, they must deliver […]
