General Modulator The phase modulation is given by Q(t) I(t) = sinφ(t) cosφ(t) = tanφ(t) or φ(t) = tan−1 Q(t) I(t) The IQ modulator is a universal digital modulator. We can draw a set of points in the IQ plane that represent symbols to transmit. For instance, if we transmit I = 0/A and Q = 0, then we have a simple ASK system (amplitude ...
