sampling rate

Posted: Sat Dec 09, 2017 5:11 pm

Following a DFT calculation of i(t) and q(t) - the separation of the spectral lines imply a sampling rate of 1.0 MHz instead of 2.0 MHz.
fsMHz=2.0; rfMHz=.85; mir_sdr_BW_0_200; mir_sdr_IF_Zero. Any help in understanding this would be appreciated.

Not certain what the issue is but doesn't a sampling rate twice that required only imply that you're over sampling? Why is this a bad thing?
