Rational resampling polyphase FIR filter.
Either taps or fractional_bw may be specified, but not both.
If neither is specified, a reasonable default, 0.4, is used as the fractional_bw.
This block only works when the output language of the flowgraph is Python.
- Interpolation factor (integer > 0)
- Decimation factor (integer > 0)
- Taps (R)
- Optional filter coefficients (sequence)
- Fractional BW
- Fractional bandwidth in (0, 0.5), measured at final freq (use 0.4) (float). In GNU Radio 3.8, the default value is 0, which should either be changed to a value 'between' 0 and 0.5; or just removed. Removing the value of fractional bandwidth will cause the block to use the default value of 0.4.
This flowgraph shows a Rational Resampler block changing the sample rate from 960 to 500.
