- * @short_description: Chebyshev band pass and band reject filter
- *
- * <refsect2>
- * <para>
- * Attenuates all frequencies outside (bandpass) or inside (bandreject) of a frequency
- * band. The number of poles and the ripple parameter control the rolloff.
- * </para>
- * <para>
- * This element has the advantage over the windowed sinc bandpass and bandreject filter that it is
- * much faster and produces almost as good results. It's only disadvantages are the highly
- * non-linear phase and the slower rolloff compared to a windowed sinc filter with a large kernel.
- * </para>
- * <para>
- * For type 1 the ripple parameter specifies how much ripple in dB is allowed in the passband, i.e.
- * some frequencies in the passband will be amplified by that value. A higher ripple value will allow
- * a faster rolloff.
- * </para>
- * <para>
- * For type 2 the ripple parameter specifies the stopband attenuation. In the stopband the gain will
- * be at most this value. A lower ripple value will allow a faster rolloff.
- * </para>
- * <para>
- * As a special case, a Chebyshev type 1 filter with no ripple is a Butterworth filter.
- * </para>
- * <para><note>
- * Be warned that a too large number of poles can produce noise. The most poles are possible with
- * a cutoff frequency at a quarter of the sampling rate.

- * Attenuates all frequencies above the cutoff frequency (low-pass) or all frequencies below the
- * cutoff frequency (high-pass). The number of poles and the ripple parameter control the rolloff.
- * </para>
- * <para>
- * This element has the advantage over the windowed sinc lowpass and highpass filter that it is
- * much faster and produces almost as good results. It's only disadvantages are the highly
- * non-linear phase and the slower rolloff compared to a windowed sinc filter with a large kernel.
- * </para>
- * <para>
- * For type 1 the ripple parameter specifies how much ripple in dB is allowed in the passband, i.e.
- * some frequencies in the passband will be amplified by that value. A higher ripple value will allow
- * a faster rolloff.
- * </para>
- * <para>
- * For type 2 the ripple parameter specifies the stopband attenuation. In the stopband the gain will
- * be at most this value. A lower ripple value will allow a faster rolloff.
- * </para>
- * <para>
- * As a special case, a Chebyshev type 1 filter with no ripple is a Butterworth filter.
- * </para>
- * <para><note>
- * Be warned that a too large number of poles can produce noise. The most poles are possible with
- * a cutoff frequency at a quarter of the sampling rate.
