Low Pass Filter
Jump to navigation Jump to search
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().
(R): Run-time adjustable
- FIR Type (R)
- Specify whether input/output is real or complex
- 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.
