Abstract: Digital filters are one of the most fundamental and cardinal components in the area of digital signal processing. They eliminate either partially or completely the noise or other undesirable ...

The historic role of IIR (infinite-impulse-response)-filter-design software is to translate a set of frequency-domain design specifications into a transfer function that is based on recognized ...

This paper mainly uses the MATLAB software to design IIR digital filter with the amplitude frequency characteristic method and zero-pole method, and then analyzes the effect of coefficient ...
