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


Similar to the Variable block, the ID will hold the values generated.
Scaling factor applied to output.
Sample Rate
Input sample rate.
Cutoff Freq
Cutoff frequency in Hz
Transition Width
Transition width between stop-band and pass-band in Hz
Type of window to use
The beta paramater only applies to the Kaiser window.
