This filter is a convenience wrapper for an Decimating FIR Filter and a firdes taps generating function of low-pass type, i.e. calling firdes.low_pass().

Parameters[edit]

(R): Run-time adjustable

FIR Type (R)
Specify whether input/output is 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.
Cutoff Freq (R)
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.

Example Flowgraph[edit]

This flowgraph shows a Low Pass Filter block.
