Digital filters are essential in signal procesing for modififying or extracting information from signals. However, quantization effects can introde distortions that affect filter performance. Understanding these effects is crial for designing effective digital filters and minimizing unwanted artifakts.

Co je to Quantization in Digital Filters?

Quantization impeves mapping a continuous range of signal amplitudes to a finite set of levels. In digital filters, this process contins during analog-to-digital conversion and with in the filter 's internal computations. Quantization introves error s known n as quantization noise, which can distort thee processed signal.
