Hi, I have a Polyphase Arbitrary Resampler block in a flow graph and I want to set the "Sample Delay" parameter so GnuRadio delays tags properly.
With the following parameters: Input Sample Rate: Fs Resampling Rate: r = output_rate / Fs Number of Filters: N Taps: taps=firdes.low_pass_2(N, N*Fs, ..., ..., ...,) The best I can figure is to set: Sample Delay: int(round((math.ceil(len(taps)/N) - 1.0)/2.0)) because GnuRadio applies this "Sample Delay" as offset to the tags before scaling the tag offsets by the resampling rate r. Can anyone confirm this is correct, or is there something I'm missing? Thank you.
