positive feedback circuit
1Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… …
2Feedback — For other uses, see Feedback (disambiguation). Feedback describes the situation when output from (or information about the result of) an event or phenomenon in the past will influence an occurrence or occurrences of the same (i.e. same defined)… …
3Feedback — Many biologic processes are controlled by feedback, just as the temperature in a home from a furnace is regulated by a thermostat. * * * 1. In a given system, the return, as input, of some of the output, as a regulatory mechanism; e.g.,… …
4feedback — i. The transmission of aerodynamic forces on control surfaces or rotor blades to cockpit controls as also the transmission of cockpit control forces to the aircraft control surfaces or rotor blades. ii. A process in an electrical circuit or… …
5feedback — /feed bak /, n. 1. Electronics. a. the process of returning part of the output of a circuit, system, or device to the input, either to oppose the input (negative feedback) or to aid the input (positive feedback). b. See acoustic feedback. 2. the… …
