Negative feedback in audio amplifiers: Why there is no ...

When the response to an unwanted disturbance is smaller with feedback applied than without it, we call it negative feedback.” Outside of audio, the subject is covered by an extremely comprehensive discipline called control theory, which deals with negative feedback around just about any process to keep it more, or even at all, stable.
Audiophile Myths About Amplifier Negative Feedback ...

The output stage isn’t infinitely fast. If you don’t want the feedback loop to overreact, you want the gain stage A to react gently at first and only add further course corrections when it sees the power stage respond. Control systems engineers like to use simple signals to test the stability of a feedback loop. A step function, say.

Is Too Much Amplifier Negative Feedback Bad? | …

It is only controversial in consumer audio, and then only specifically in power amplifiers. This dates from early solid state amplifiers that were thought to use a lot of feedback, but that only did so at really low frequencies. Over most of the audio range the feedback loop didn’t do much. Unsurprisingly those amplifiers sounded rather bad.

Negative feedback turns a high-gain amplifier with poor linearity into a lower-gain amplifier with much better linearity. This works very well as long as the delay in the feedback loop is short compared to the signal frequency.
Negative Feedback - Learn About Electronics

DC negative feedback , is used in stabilising the biasing of amplifiers against drift due to thermal effects etc. Because negative feedback amplifiers often use direct coupling and may have several stages of amplification, stable bias conditions are essential. Very small changes in …
4.4 Global Negative Feedback in a vacuum tube amplifier ...

A technique to reduce distortions, across all amplifier stages, is the global negative feedback. The effect of the global negative feedback can be explained intuitively as follows. Global negative feedback consists in using a negative feedback loop, which subtracts the output signal, appropriately attenuated, from the input signal. If the input and the output signals have …
How Negative Feedback Loops Work in the Body
https://www.verywellhealth.com/what-is-a-negative-feedback-loop-3132878
A negative feedback loop, also known as an inhibitory loop, is a type of self-regulating system. In a negative feedback loop, increased output from the system inhibits future production by the system. The body reduces its own manufacturing of certain proteins or hormones when their levels get too high.
Examples of Negative Feedback Loops
https://examples.yourdictionary.com/examples-of-negative-feedback.html
A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
