4. Branch 2: x(t)cos(2*pi*fc*t) * sin(2*pi*fc*t) --> LPF --> 0 (since cos and sin are orthogonal) --> FPGA
5. Since Daughter board is doing direct conversion, no mixing in FPGA (i.e) in DDC.
6. In PC, I will have I component as x(t) and Q component as 0 for AM modulated signal.
Is my understanding correct?
Similarly if I take OFDM modulated signal -- xr(t)cos(2*pi*fc*t) -
xi(t)sin(2*pi*fc*t) -- output at Daughter board will be xr(t) at I
component and xi(t) at Q component. This will be send to PC. Is it
