Frequency response - Frequency response is the measure of any system's response at the output to a signal of varying frequency (but constant amplitude) at its input. It is usually referred to in connection with electronic amplifiers and similar systems.

Full frequency response - If a sound is said to have Full Frequency Response, then the sound is composed of sounds from across the entire audible spectrum.The human hearing amplitude varies between 20 Hz and 20 KHz.

Treble response - Treble response is the high frequency portion of an audio system's frequency response.

Nichols plot - A Nichols plot is a graph used in signal processing in which the magnitude and phase of a frequency response are plotted on orthogonal axes. This plot combines the two types of Bode plot — magnitude and phase — on a single graph, with frequency as a parameter along the curve.
