Band Pass Filter

This filter is a convenience wrapper for an FIR Filter and a firdes taps generating function of band-pass type, i.e. calling firdes.band_pass or firdes.complex_band_pass.

Parameters
(R): Run-time adjustable


 * FIR Type (R)
 * Specify whether input/output is real or complex, and if the taps are real or complex.


 * Decimation
 * Decimation rate of filter, must be an integer, and cannot change in realtime.


 * Gain (R)
 * Scaling factor applied to output.


 * Sample Rate (R)
 * Input sample rate.


 * Low Cutoff Freq (R)
 * Lower cutoff frequency in Hz


 * High Cutoff Freq (R)
 * Upper cutoff frequency in Hz


 * Transition Width (R)
 * Transition width between stop-band and pass-band in Hz


 * Window (R)
 * Type of window to use


 * Beta (R)
 * The beta paramater only applies to the Kaiser window.
