If a microphone picks up the amplified sound output of loudspeakers in the same circuit, then howling and screeching sounds of audio feedback (at up to the maximum power capacity of the amplifier) will be heard, as random noise is re-amplified by positive feedback and filtered by the characteristics of the audio system and the room. In electrical switches, including bimetallic strip based thermostats, the switch usually has hysteresis in the switching action. ['fidbk'] the process in which part of the output of a system is returned to its input in order to regulate its further output. Amplifiers may oscillate gently in ways that are hard to detect without an oscilloscope, or the oscillations may be so extensive that only a very distorted or no required signal at all gets through, or that damage occurs. Cultural anthropology: A contemporary perspective (2nd ed.) Anagrams In these cases hysteresis is mechanically achieved via positive feedback within a tipping point mechanism.

[2], Such systems can give rich qualitative behaviors, but whether the feedback is positive or negative in sign is an extremely important influence on the results. When the loop gain is positive and above 1, there will typically be exponential growth of any oscillations or divergences from equilibrium. not capable of being challenged or proved wrong, 'Dunderhead' and Other Nicer Ways to Say Stupid, 'Pride': The Word That Went From Vice to Strength. In most cases, such feedback loops culminate in counter-signals being released that suppress or breaks the loop. A viral video is an example of the network effect in which links to a popular video are shared and redistributed, ensuring that more people see the video and then re-publish the links. When the gain of the feedback loop is above 1, then the output moves away from the input, if it is above the input, then it moves towards the nearest positive limit, if it is below the input then it moves towards the nearest negative limit. .

They all use positive feedback to create oscillations. These factors amount to an inefficiency, but they are necessary to avoid instabilities. While there may have been periods of time such as the exit from an ice age where the gain was greater than one, this has not lasted long enough for extreme effects such as the evaporation of the oceans as is believed to have happened on Venus. Positive feedback is communication that highlights a person's strengths and achievements. Working memory, the cognitive functions of the cerebellum and the child prodigy.

This is the basis for many social phenomena, including Ponzi schemes and chain letters. Noun Phrase Help other members in your team or department improve by offering positive feedback and suggestions. If the loop gain (the product of the amplifier gain and the extent of the positive feedback) at any frequency is greater than one, then the amplifier will oscillate at that frequency (Barkhausen stability criterion).
