Detailed Description

Second-order band-stop filter.

This file defines the filter::band_stop::BSF_2 class, which implements a discrete-time second-order band-stop filter.

The filter attenuates frequency components within a specified frequency band while allowing frequencies below and above the stopband to pass.

The filter is parameterized by its center frequency, bandwidth, and sampling time. The quality factor is derived from the center frequency and bandwidth.

The implementation maintains previous input and output samples as internal filter state.

The class is templated to support different numeric types such as float and double.

Template Parameters

T	Numeric data type used for the filter calculations.
