Signal to noise ratio (abbreviated SNR) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.

Adaptive DPCM (ADPCM) is a variant of DPCM that varies the size of the quantization step, to allow further reduction of the required bandwidth for a given signal to noise ratio.

Quality of service comprises requirements on all the aspects of a connection, such as service response time, loss, signal to noise ratio, crosstalk, echo, interrupts, frequency response, loudness levels, and so on.

The ratio of the two is called the gyromagnetic ratio and is simply the half of the charge to mass ratio.

Biology A recognition signal is also a chemical signal used in biology to signal the end of a section of DNA or RNA during gene duplication in cells.

Once the signal is digitized, the PCM signal is usually subjected to further processing (e.g., digital data compression).

The analog signal is frequency modulated and is converted from an FM signal to what is referred to as baseband.

It's a signal to noise problem. Okay?

So Western diplomats who negotiate with China should call lower level officials bluff, and focus on the signal to noise ratio, bearing in mind that, ultimately, decisions are taken quietly at a higher level by pragmatic leaders who are indeed susceptible to pressure.

Profitability index (PI), also known as profit investment ratio (PIR) and value investment ratio (VIR), is the ratio of payoff to investment of a proposed project.

Unlike metadata that is added to the carrier signal, a digital watermark does not change the size of the carrier signal.

The signal was red.

They were watching for the signal to start.

Sometimes a channel may contain an MTS signal, which offers more than one audio signal by adding one or two subcarriers on the audio signal, each synchronized to a multiple of the line frequency.

Overall pressure ratio is 28.0, with a bypass ratio of 4.66.

Overall pressure ratio is 30.4, with a bypass ratio of 5.15.

On 20 May 2003, the station had used four new frequencies that had caused interference on Cuban radio transmissions and had availed itself of a United States Air Force plane to transmit the television signal at peak viewing time, using channels reserved by law for Cuban stations.

In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.

In aerodynamics, the aspect ratio of a wing is the ratio of its length to its breadth (chord).

The electronics involved in producing an accurate analog signal from the discrete data are similar to those used for generating the digital signal.

It is also my proposal to signal any violations.

Abort signal from abort(3)

Timer signal from alarm(2)

That was a useful signal.

A continuous signal or a continuous time signal is a varying quantity (a signal)whose domain, which is often time, is a continuum (e.g., a connected interval of the reals).

In fact, MG causes the motor neuron action potential to muscular twitch ratio to vary from the nonpathological one to one ratio.

The ratio of this air to the amount of air flowing through the engine core is the bypass ratio.

The increase in core size and overall pressure ratio raised the core flow, decreasing the bypass ratio to 4.26.
