WebMay 18, 2013 · Dithering is one way, as in "rawb"'s answer. In audio, the usual accepted standard for plain dithering was a triangular PDF dither with a peak-peak amplitude of 1 LSB, added to the high res (e.g. analog) signal before quantisation (e.g. the ADC). WebNov 2, 2014 · The act of dithering helps this process by decorrelating the quantization noise. Consider a simple example where a constant (not sinusoidal) signal is sent into a 1bit ADC. If the signal is at 0.75 (ignore units) and the ADC can, depending on its input, either output a 0.0 or 1.0, the signal will be reported as a 1.0 till the cows come him.
