I study data sheet of AD9142 that have instructions " NCO modulator Block Diagram ". I don't understand some function for NCO modulator , if NCO modulator in I/Q output mode , then the I DATA OUT is real part IF signal or not ? Thank you.
Yes, both the input and output and the NCO are a complex signal. "I" stands for In-Phase, which is the real part and "Q" stands for Quadrature, which is the imaginary part.
I am understand. Thank you for your help. Thank you.
