Band-reject Filter Taps

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.
