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

Parameters

(R): Run-time adjustable

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