Discontinuous Samples

I have noticed that both the i and q samples are discontinuous sample to sample. These discontinuities are significant and observed by connecting two or more samples together. I have observed this for mir_sdr_BW_0_600 and mir_sdr_BW_0_200 using mir_sdr_IF_0_450. If I use mir_sdr_IF_1_620 then there ...

sampling rate

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.

Basic Questions

Many, many thanks for providing the api. 1. In the MSi2500 data sheet, a dsp block is shown. What's happening there? 2. What does zero IF mean? 3. It would be helpful to know the bandwidth of I(t) and q(t), and it's frequency range. 4. I have started out with Fs=2MHz, Frf=1.0MHz, and zero if. Many t...
