Frequency response is the quantitative measure of the output spectrum of a system or device in response to a stimulus, and is used to characterise the dynamics of the system. It is a measure of magnitude and phase of the output as a function of frequency, in comparison to the input. In simplest terms, if a sine wave is injected into a system at a ...

A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz ± 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level.

A graph which shows how a system or piece of equipment or even an environment such as a room responds to different frequencies. Ideally, for audio work the graph should plot a flat line from below 20 Hz to above 20 kHz. In practise this is often not achieved, and the line will fluctuate up and down between these points, indicating that the equipmen...
