Summary¶
The difference between the ideal mathematical value and the actual value as processed in fixed-point arithmetic is known as quantization noise. There are many factors that can influence the level of the quantization noise, some of which that affect biquad filters are discussed below. This note focuses on Biquad filters as they have a feedback component in them that can amplify the noise.
