Thank you all for the comprehensive answers. My question is much simpler and very practical: if phase shift between I and Q channels is always decreasing, then the...
For SSB (Single Side Band) modulation I use Prosch’s [1] IIR
all-pass filters as per below:For a single Cosine tone, with a frequency from the range
above, the...
does it mean that if in SDR radio I sample output of quadrature detector with 16bit ADC at 48kHz, then downsample and average to 12kHz, I increase sensitivity in...
Probably tone filters with envelope detectors, on the intermediate frequency, would work in this case.
Random hopping is happening with the constant rate, which is 20 kHz in my example.I don't have sampling rate for now, I consider the analog RF signal, as generated...
Yes, it reminds me kFSK, where k is the number of frequencies, 16 in my example F0 + [500:300:5000] . There is a lot of theory about 16FSK, but no information on...
