Veening,J., Smits, W.K., and Kuipers, O.P. positive feedback - feedback in phase with (augmenting) the input regeneration feedback - the process in which part of the output of a system is returned to its input in order to regulate its further output A Ponzi scheme is a good example of a positive-feedback system, because its output (profit) is fed back to the input (new investors), causing rapid growth toward collapse. [6] In contrast, a system that has negative gain around the loop has negative feedback.[1][2]. H.S. Microphones are not the only transducers subject to this effect. A daily challenge for crossword fanatics. The problem with regenerative amplifiers working at these very high gains is that they easily become unstable and start to oscillate. An amplifier that is stable in one set of conditions can break into parasitic oscillation in another. Random motions in molecular dynamics coupled with positive feedback can trigger interesting effects, such as create population of phenotypically different cells from the same parent cell. noun.

Noun Phrase Provide positive feedback to your students when appropriate. 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). When you provide positive feedback, you are telling your team members what they're doing correctly and should continue to do. For example, beginning at the macro level, Alfred J. Lotka (1945) argued that the evolution of the species was most essentially a matter of selection that fed back energy flows to capture more and more energy for use by living systems. Accessed 4 Nov. 2022. regeneration. ['pztv'] involving advantage or good. adjective. | When an input voltage is expected to vary in an analogue way, but sharp thresholds are required for later digital processing, the Schmitt trigger circuit uses positive feedback to ensure that if the input voltage creeps gently above the threshold, the output is forced smartly and rapidly from one logic state to the other. However if the input goes past the limit,[clarification needed] then the feedback will change sign[dubious discuss] and the output will move in the opposite direction until it hits the opposite limit. While in some cases nearly identical to positive, cocksure implies presumptuous or careless positiveness. ['pztv'] formally laid down or imposed.
