Maximum output of an electronic device or recording medium compared to its noise floor or level of background noise. S/N ratios are measured in decibels (dB), and larger numbers are better. A S/N ratio of 100 dB means that the maximum signal output is 100 decibels above the noise floor, or the point at which the signal will be obscured by noise (low-level hum and other electrical interference that is part of the component).
a measurement of the noise level in a signal expressed in dB (decibels). In a video signal, values from 45dB to 60dB produce an acceptable picture. Less than 40dB is likely to produce a 'noisy' picture.
Indicates the ratio of noise to actual total signal (in a video or audio signal generally speaking). The S/N number measures how much higher the signal level is to the level of background electronic noise, so a higher number means a clearer and crisper picture. Signal-to-noise ratio is expressed in decibels (dB).
The ratio between useful video signal and unwanted noise. The higher the number, the better the image quality.
The ratio of the signal voltage or power, to the noise voltage or power.
(signal-to-noise ratio) - The range, usually expressed in decibels, between the loudest sound a recording medium can accommodate and its background noise level.
See Signal-to-noise ratio.
Measure of noise levels of a video signal; the higher the number the better.
Signal to noise ratio. The more signal you can record and the less noise, the higher quality the recording will be.
Signal-to-Noise Ratio.The amount of communication signal in relation to the amount of interference, or noise, on the medium.It is usually expressed in decibels.
(Signal-to-Noise) Ratio of signal (electrical impulses carrying information) to noise (impurities in signal). In television and VCRs, the ratio of the maximum peak-to-peak voltage of the video signal to the voltage of the noise, is expressed in decibels. The higher the video S/N, the cleaner the picture.
Signal-to-Noise Ratio. The ratio, measured in decibels, between the maximum signal level and the noise level with no signal present. The higher the value, the better the sound reproduction.
Stands for Signal to Noise ratio. This is calculated with the logarithm of the normal signal and the noise RMS value.
Signal-to-Noise ratio is the amount of desired signal as compared to undesired signal. In video Tape, noise appears as "snow," audio noise is the tape hiss heard upon playback. A way of measuring how good a picture or a sound will be.e The higher the ratio between the desired type of signal and the unwanted noise, the better the results.
