So according to the link the library doesn't utilize one particular algorithm but is optimized to use the "best" algorithm depending on n according to this link https://cnx.org/contents/ulXtQbN7@15/Implementing-FFTs-in-Practice So, is there any particular way to figure out which algorithm is us

Might work for you: Any kind of source, throttled to 1/HEARTBIT_INTERVAL, to a UDP sink. Example: Constant Source(1) -> Throttle (1 S/s) -> UDP Sink will write the number 1 to the designated UDP sink, once every second. On Sun, Apr 1, 2018 at 12:22 AM Milos Milosavljevic < milos.milosavlje...@spi

Hi All, I was wondering if someone can give me some hints on the below please. I have a flowgraph running continuously demodulating some off air signals and spitting out meta data about the parameters, calculated SNRs, BER, freq offset estimations, etc. That meta and output data is parsed regular
