What's SNR to ah

signal to noise ratio, that is, SNR (Signal to Noise Ratio), also known as SNR, in the narrow sense of the term refers to the amplifier The output voltage and at the same time the output voltage noise ratio, often expressed by a few decibels.Device-to-noise ratio, the higher that it generated less noise.In general, the greater the signal to noise ratio to show mixed signals in the noise The smaller, sound playback, the higher the quality of the sound, otherwise the contrary.
