Hello everyone,
For my program, in every 20 ms, I need to choose 60% of data in the stream (I marked them with stream tags "start" and "stop"), then do FFT and plot, and discard the following 40%. Is it possible to do all of this in gnuradio with OOT blocks?
I was thinking of keep M in N, but when I look at the block introduction, I am worried that it may cause inaccuracy due to the changed data interval?
I am also looking at ZMQ sink, to send truncated data to an external Python code for FFT, but my sample rate is quite high, I am afraid the python code can't handle it.
Please could you guide me in the right direction to do it properly?
Thank you and best regards,
Wei
