“How can we fix signal noise by inducing noise?”

 

When converting a signal from a higher-bit to a lower-bit resolution, unpleasant noise can be induced. To fix this, we can add in some low-volume noise called Dither before the conversion, effectively eliminating the truncation error. Dithering is commonly used in audio sampling during file compression.
