A measurement of the noise level in a signal expressed in dB (decibels). The higher the Signal to Noise ratio, the better the quality of the signal.
This is tech speak for the ratio of wanted signal to background noise, like hiss and hum. This wants to be a high as possible, so signals do not get lost in the noise. What this means is that you should have everything turned up as far as possible without' going into the red' , or causing distortion. .
The difference between the level of the Audio Signal and the level of unwanted noise in that Signal. The higher the Figure, which is Measured in dB, the lower the unwanted noise in that Signal. Eg- S/N Ratio of 105dB is better than S/N Ratio of 93dB.
A comparison of the signal level relative to the noise level. Larger numbers are better.
This is simply ratio of the signal power and noise power, expressed in decibels (dB).
A measure in decibels of the ability to differentiate the signal being sent from interference or noise in the transmission channel. In amplified systems, such as long distance terrestrial circuits or satellite circuits, the noise is amplified along with the signal.
The ratio of the strength of the signal for information content in the image to the noise level (the standard deviation of the signal).
The ratio between the nominal level of a signal (0 dBm) and the general circuit noise level (noise floor) measured in dB. All electronic devices produce noise. The S/N ratio is a measure of how quet the device is by indicating how low the level is of the inherant noise.
This is the ratio between the signal strength and the noise levels on an audio or video signal.
It is the ratio between the signal voltage and the noise voltage generated by an electronic circuit. It is measured in decibels (dB).
This is an expression of the mixture of music to noise. The less noise, the higher the number. A good signal-to-noise ratio specification for an amplifier is 100dB or higher.
SNR is the ratio of the RMS value of the measured output signal to the RMS sum of all other spectral components below the Nyquist frequency, excluding the first six harmonics and DC. The value is expressed in decibels.
Is the relationship of signal amplitude to noise voltage amplitude. It is expressed in decibels (dB).
The ratio of power of a signal to the unwanted interference mixed in with it. It measures the clarity of a signal in a circuit, and is represented in decibels. The greater the ratio, the less noise that is present and the easier it can be filtered out.
This is a ratio between the signal strength and the noise levels of an audio or video signal.
of a sound measures the difference in decibels between the average signal amplitude and the average noise amplitude. The higher the ratio, the lower the noise floor, the better the sound. '
An old electrical engineering term, describing the ratio of desirable information (signal) to undesirable information (noise). It gets pretty low at times on the Net.
The difference between the nominal signal level and the residual noise floor, usually expressed in decibels.
The sound level of a speaker above background noise, at the listener's ear level. The inverse square law impacts the S/N ratio.
Abbr: S/N ratio, measured in dB, it is an indication of the level of unwanted background noise generated by a hi-fi component (eg a tuner or amplifier). Again, the higher the number the better.
The ratio of the overall RMS signal level to the RMS noise level, expressed in dB.
The ratio of the magnitude of a desired signal to that of noise.
This is the ration of music versus background noise. The better the SNR ratio, the higher the quality of music that you will get.
How much relevant content (signal) something has compared to non-relevant content (noise); expressed in decibels.
Is a measure of Signal to Noise in an audio or video program. In audio and video signal-to-noise is measured in decibels (dB). 6db is twice as loud as 3db. To put signal to noise ratio in a more understandable way, it is a way of measuring how clean a signal is. The higher signal to noise ratio the cleaner the signal, which makes for improved listening.
The amount of signal (dBV) above the noise floor when a specified sound pressure level is applied to the microphone (usually 94 dB SPL).
Measured in decibel units (dB), the SNR is the amount of noise added by the electrical circuit reproducing the audio signal.
The sound level at the listeners ear of a speaker above the background noise level. The inverse square law impacts the S/N ratio.
Signal to Noise Ration is the ratio of the strength of the desired signal to the strength of any noise present, measured in decibels.
Measured in decibels, this is the difference between the signal strength a system reproduces compared to the strength or amplitude of its background noise.
A digital image is a digital signal. Signal-to-noise ratio is the ratio of undesired data to desired data.
Measure of the amount of noise that has been added to a message during transmission. See: channel, information theory.
(SNR) Commonly used interchangeably with ACR
Ratio between a useful video signal and unwanted noise. Usually expressed in db (decibels).
The numerical relationship of signal information to extraneous line noise. Too much noise (low signal-to-noise ratio) can cause the original signal to be lost, since it cannot be distinguished from the line noise.
We define this as the signal (max minus min) divided by an estimate of variability (or noise) such as the standard deviation of the max controls or the standard deviation of max minus min. There is some disagreement over the meaning of this term.
A measurement of how strong the desired target signal is, compared to the level of background noise.
The ratio between a useful video signal and unwanted noise.
The ratio of the signal power and noise power. A video S/N of 54 to 56 dB is considered to be an excellent S/N, that is, of broadcast quality. A video S/N of 48 to 52 dB is considered to be a good S/N at the headend for Cable TV.
A measure of useful signal to unwanted noise. When computed using sound levels in units of dB, it is a subtraction and not a ratio. SNR = LS - LN where LS is the level of the signal and LN is the level of the noise.
Signal to noise ratio refers to how much relevant content (signal) something has as opposed to non-relevant content (noise). The term is from radio, but can also be applied to newsgroups. The "signal" in a newsgroup is regular postings which are on-topic. The "noise" in a newsgroup is everything else that does not help contribute to the purpose for which the newsgroup was created (i.e. a mutually beneficial discussion about a certain specific topic). Note that spam postings are not the only noise: off topic-postings, flames, "posting tests" and other things can also be defined as noise. Generally, however, nothing has lowered the signal to noise ratio in all of usenet like spamming has.
This is a camera rating that measures how much noise will be in the picture. The higher the rating the less noise will be in your video.
This value represents how much signal noise the camera can tolerate and still provide a high quality picture. The higher the number the better.
Relative power of the signal to the noise. As the ratio decreases on a line, it becomes more difficult to distinguish between information and non-information (noise). S/N deteriorates with distance because the noise builds every time the signal is repeated.
The ratio of the amplitude of the desired signal to the amplitude of noise signals at a given point in time. SNR is usually expressed in dB.
Ratio of the magnitude of the signal to the magnitude of noise usually expressed in decibels.
The sensitivity of a communications receiver is generally specified in terms of the audio signal-to-noise ratio that results from an input signal of a certain number of microvolts.
