Band-pass Filter Taps

Generates taps for a band-pass filter and stores it in variable called whatever the ID is set to. It's essentially a convenience wrapper for calling firdes.band_pass or firdes.complex_band_pass. None of the parameters are realtime changeable because the taps are created once at the beginning of the flowgraph.

Parameters

 * ID
 * Similar to the Variable block, the ID will hold the values generated.


 * Tap Type
 * Whether the taps are real or complex.


 * Gain
 * Scaling factor applied to output.


 * Sample Rate
 * Input sample rate.


 * Low Cutoff Freq
 * Lower cutoff frequency in Hz


 * High Cutoff Freq
 * Upper cutoff frequency in Hz


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


 * Window
 * Type of window to use


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