Is the reversal of flow within a dynamic compressor that takes place when the capacity being handled is reduced to a point where insufficient pressure is being generated to maintain flow Also known as surge (030)
Pumping a tank consists of using a pump to transfer liquid from the tank to sea, from sea to tank, or from one tank to another The tanks must be vented during this operation
Undesirable and objectionable gain or background noise level changes in a companding system A slower, somewhat less noticeable form is called breathing Back to top Quadrature Detector A type of FM demodulator
The action of an oscillator that provides cyclic inputs to an oscillating reaction device Note: Examples of pumping are the action that results in amplification of a signal by a parametric amplifier, and the action that provides a laser or maser with an input signal at the appropriate frequency to sustain stimulated emission
