Highest available Signal-To-Noise performance delivering. peak signal-to-noise ratio, often abbreviated psnr, is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. because many signals have a very wide dynamic range, psnr is usually expressed in terms of the logarithmic decibel scale., in electronics and radio, the ratio of desired electronic signals to unwanted noise can vary over an extremely wide range, up to a billion times or more. the calculation for the signal-to-noise ratio (snr) is either the difference of two logarithms or the logarithm of the ratio of the main and noise signals.).

r = snr(x,y) returns the signal-to-noise ratio (SNR) in decibels of a signal, x, by computing the ratio of its summed squared magnitude to that of the noise, y. y must have the same dimensions as x.Use this form when the input signal is not necessarily sinusoidal and you have an estimate of the noise. Likewise the signal-to-noise ratio is also в€љ 10,000 = 100. If the average number of electrons per well is increased to one million, both the standard deviation and the SNR increase to 1,000. That is, the noise becomes larger as the signal becomes larger, as shown in Fig. 25-9b.

W e hav e introduced a measure that indicates the local signal to noise ratio. This is in contrast to the standard signal to noise ratio that relates the global prop erties of the signal and noise. For a random noise (which is usually the case) the signal-to-noise ratio increases as the square root of the number of averaged data, as was discussed in Section 4.1.3. For example, averaging 4 measurements, one can improve signal-to-noise ratio twice, averaging 100 measurement will reduce the noise level 10 times, and so on.

Likewise the signal-to-noise ratio is also в€љ 10,000 = 100. If the average number of electrons per well is increased to one million, both the standard deviation and the SNR increase to 1,000. That is, the noise becomes larger as the signal becomes larger, as shown in Fig. 25-9b.
