Feedback — 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)… … Wikipedia
Negative feedback amplifier — Figure 1: Ideal negative feedback model A negative feedback amplifier (or more commonly simply a feedback amplifier) is an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.… … Wikipedia
Current-feedback operational amplifier — Representative schematic of a current feedback op amp or amplifier. The current feedback operational amplifier otherwise known as CfoA or CfA is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage… … Wikipedia
Electronic feedback loops — are used to control the output of electronic devices, such as amplifiers. A feedback loop is created when all or some portion of the output from an electronic device is fed back to the input. A device is said to be operating open loop if no… … Wikipedia
Negative feedback — Most endocrine hormones are controlled by a physiologic negative feedback inhibition loop, such as the glucocorticoids secreted by the adrenal cortex. The hypothalamus secretes corticotropin releasing hormone (CRH), which directs the anterior… … Wikipedia
Positive 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… … Wikipedia
Bridged and paralleled amplifiers — Multiple electronic amplifiers can be connected such that they drive a single floating load (bridge) or a single common load (parallel), to increase the amount of power available in different situations. This is commonly encountered in audio… … Wikipedia
Crate Amplifiers — is a company that produces electric guitar amplifiers. Early Crate Amps In the late 1970 s, Crate made amplifiers that actually looked like wooden crates. They were manufactured with the same sort of chest handles found on military footlockers.… … Wikipedia
Dumble Amplifiers — Tom McGrath s Dumble ODS 50W Combo Converted to Head and Cabinet by Doug Stalters of Vintone Circuits Dumble musical instrument amplifiers are custom manufactured in very limited numbers by Alexander Howard Dumble of Los Angeles, California.… … Wikipedia
Audio feedback — (also known as the Larsen effect after the Danish scientist, Søren Larsen, who first discovered its principles) is a special kind of positive feedback which occurs when a sound loop exists between an audio input (for example, a microphone or… … Wikipedia
Multiple feedback topology (electronics) — Multiple feedback topology is an electronic filter topology which is used to implement an electronic filter by adding two poles to the transfer function. A diagram of the circuit topology for a second order low pass filter is shown in the figure… … Wikipedia
