Hello-
when creating a flowgraph in GRC there are times I would like to change the decimation on-the-fly with a gui slider. However, this does not work because the decimation factor in blocks such as the AM Demod or Decimating Fir Filter does not have an internal callback (as I understand it). My main purpose is to be able to dynamically change the sampling rate to re-scale the x-axis in a gui fft sink while the flowgraph is operating. Is there a way around this? Is this a necessary limitation, or just something nobody has gotten around to implementing?
