Determining the Need for Dither When Re-Quantizing a 1-D Signal

This poster presents novel methods for determining if dither is needed when reducing the bit depth of a one dimensional digital signal. These are statistical based methods in both the time and frequency domains, and are based on determining whether the quantization noise with no dither added is whit...
