ABSTRACT:
A method for slewing a bandwidth characteristic of a digital filter within a range between a first bandwidth characteristic and a second bandwidth characteristic. The digital filter includes a plurality of cascaded filter sections and each of the sections has respective coefficients. The method establishes a polynomial having an order greater than or equal to two for modeling a changing value of one of the coefficients at the bandwidth characteristics within the range. An index value is determined for identifying a desired bandwidth characteristic within the range. The index value is input into the polynomial to obtain a corresponding coefficient value for the one coefficient. The coefficient value is then loaded into a respective filter section.
