WebThe dither signal can be at half sampling frequency and have an amplitude equal to half a quantising step together with white noise at a level of 4dB below the inherent quantising noise. In practice for point to point links, a single parity check digit is added to each 13 bit sample word. ... FFT is a fast, easy and robust numerical approach to ...
