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.

Parameters[edit]

(R): Run-time adjustable

Interpolation
Interpolation factor (integer > 0)
Decimation
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)

Example Flowgraph[edit]

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