In theprevious postthe Python scipy.signaliirdesignfunction was disected. We reviewed the basics of filter specification and reviewed how to use theiirdesignfunction to design IIR filters. Theprevious postI only demonstrated low pass filter designs. The following are examples how to use theiirdesignf...

This then leads to compact update expressions such asy += b * (x - y), in programming languages that support the+=-operator (see the Python code below for an example). Impulse Response For windowed-sinc filters (see, e.g.,How to Create a Simple Low-Pass Filter), the impulse response...
