Definition of "signal to noise ratio" |
Signal to Noise Ratio, the ratio of the amplitude of the desired signal to the amplitude of noise signals at a given point in time. The larger the number, the better. Usually expressed in dB. / Signal to Noise Ratio is final relationship between the video or audio signal level to the noise level. Ratio of the signal power to the noise power in a specified bandwidth, expressed in dBW. / Data Encryption Standard is a previously predominant symmetric-key algorithm for the encryption of electronic data. It was highly influential in the advancement of modern cryptography in the academic world. / ratio of the magnitude of the signal to the magnitude of noise usually expressed in decibels. |
Definition of "Signal-to-Noise Ratio" |
Signal-to-Noise Ratio, the ratio of the amplitude of the desired signal to the amplitude of noise signals at a given point in time. The larger the number, the better. Usually expressed in dB. / The ratio of the electrical output signal to the electrical noise generated. The ratio of the amplitude of the desired signal to the amplitude of noise signals at a given point in time. SNR is expressed as 20 times the logarithm of the amplitude ratio, or 10 times the logarithm of the power ratio. |
