Audio system measurements — are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Signal noise — In science, and especially in physics and telecommunication, noise is fluctuations in and the addition of external factors to the stream of target information ( signal ) being received at a detector. In communications, it may be deliberate as for … Wikipedia
Audio converter — In signal processing, an audio converter or digital audio converter is a type of electronic hardware technology which converts an analog audio signal to a digital audio format, either on the input (Analog to digital converter or ADC), or the… … Wikipedia
Noise (audio) — Noise in audio, recording, and broadcast systems refers to the residual low level sound (usually hiss and hum) that is heard in quiet periods of a programme. In audio engineering, it can refer either to the acoustic noise from loudspeakers, or to … Wikipedia

Carrier-to-noise ratio — In telecommunications, the carrier to noise ratio, often written CNR or C/N , is the signal to noise ratio (SNR) of a modulated signal. The CNR is the quotient between the average received modulated carrier power C and the average received noise… … Wikipedia
