Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
This flowgraph shows a Rational Resampler block changing the sample rate from 960 to 500.

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

(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

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