Phase response, the Glossary
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]

7 relations: Amplifier, Filter (signal processing), Group delay and phase delay, Phase (waves), Signal, Signal processing, Sine wave.
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.

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.
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.
