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.
- 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)
This flowgraph shows a Rational Resampler block changing the sample rate from 960 to 500.
