amplifier response
21Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
22Magnetic amplifier — The magnetic amplifier (colloquially known as a mag amp ) is an electromagnetic device for amplifying electrical signals. The magnetic amplifier was invented early in the 20th century, and was used as an alternative to vacuum tube amplifiers… …
23Headphone amplifier — A headphone amplifier is a kind of audio amplifier designed particularly to drive headphones instead of loudspeakers. Most commonly they are found embedded in electronic devices such as integrated amplifiers, portable music players and… …
24Cochlear amplifier — The cochlear amplifier was first proposed in 1948 by T. Gold[1]. This was around the time when Georg von Békésy was publishing articles observing the propagation of passive travelling waves in the dead Cochlea. Thirty years later the first… …
25Auditory brainstem response — The auditory brainstem response (ABR) is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp. The resulting recording is a series of vertex positive waves of which I …
26Image response — (or more correctly, image response rejection ratio, or IMRR) is a measure of performance of a radio receiver, particularly one that operates on the super heterodyne principle.In such a radio receiver, a local oscillator is used to heterodyne or… …
27Phase response — is the relationship between the phase of a sinusoidal input and the output signal passing through any device which accepts input and produces an output signal such as an amplifier or a filter.Amplifiers, filters and other devices are often… …
28frequency response — noun Date: 1926 the ability of a device (as an audio amplifier) to handle the frequencies applied to it; also a graph representing this ability …
29frequency response — noun Electronics the dependence on signal frequency of the output–input ratio of an amplifier or other device …
30Bode plot — ; the straight line approximations are labeled Bode pole ; phase varies from 90° at low frequencies (due to the contribution of the numerator, which is 90° at all frequencies) to 0° at high frequencies (where the phase contribution of the… …
