My first idea above was to produce the sine wave from the lookup
table (which i have generated with the python code line before)
with a python script on the command line only for an single
experiment for understanding how to do this without gnuradio.
My first idea is: python has to sample the
256 samples (for one period) from lookup table in exactly one
second. So i think i need a timer which calls the next sample in
the lookup table all 3,9 ms.
Yes, meanwhile i know this :-)
GNU Radio is NOT a system where samples are processed
sample-by-sample, with a fixed precise sampling rate. Each block
is just asked to process/generate/sink as many samples as
possible, and the result is passed on to the next block as fast as
thanks and regards,
