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.
