Phase response, the Glossary

Index Phase response

In signal processing, phase response is the relationship between the phase of a sinusoidal input and the output signal passing through any device that accepts input and produces an output signal, such as an amplifier or a filter.[1]

Amplifier

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current).

See Phase response and Amplifier

Filter (signal processing)

In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Phase response and filter (signal processing) are signal processing.

Group delay and phase delay

In signal processing, group delay and phase delay are two related ways of describing how a signal's frequency components are delayed in time when passing through a linear time-invariant (LTI) system (such as a microphone, coaxial cable, amplifier, loudspeaker, telecommunications system, ethernet cable, digital filter, or analog filter). Phase response and group delay and phase delay are signal processing.

Phase (waves)

In physics and mathematics, the phase (symbol φ or ϕ) of a wave or other periodic function F of some real variable t (such as time) is an angle-like quantity representing the fraction of the cycle covered up to t. It is expressed in such a scale that it varies by one full turn as the variable t goes through each period (and F(t) goes through each complete cycle). Phase response and phase (waves) are wave mechanics.

See Phase response and Phase (waves)

Signal

Signal refers to both the process and the result of transmission of data over some media accomplished by embedding some variation. Phase response and Signal are signal processing.

See Phase response and Signal

Signal processing

Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements.

Sine wave

A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. Phase response and sine wave are trigonometry and wave mechanics.
