Indeed I have since checked any source of crosstalk and removed all links from
source to audio sink but the one going to input number 3 and still the same
issue is observed. However remplacing 9 Hz output (at 192000 Hz sampling
rate) with 9.1 Hz solves the issue of the unexpected shape at
I see a lot of inputs to the sound card sink in the flowgraph.. could the
signal be getting mixed with itself among the many inputs to the card and
causing new frequency components as it gets mixed? Can you try sending the
flow graph signal to just one sink input at a time (perhaps using a
constant
I have a funny problem with the output of a sound card fed from a signal
source.
The hardware setup is a Scarlett 18i8 sound card sampled at 192 kHz (for VLF
signal analysis) with the signal generated from the front output number 1
(channel number 3 in the GNURadio audio sink).
The sound card
