Analog Filter Functions
``` ```This section presents functions for creating and converting several kinds of analog filter transfer functions that are commonly used in signal processing applications. Particularly, these functions create analog prototypes that can be used as inputs to the various IIR filter routines for conversion to digital filters. ``` ```ANALOG FILTER DESIGN ``` ```Normalized Filter Design Functions
