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 thanks in advance for help with these basic questions.
