Hello,
Recently at college we've been looking at QPSK, PSK, BPSK, etc. And I've been trying to find circuit that perform this type of modulation and learn on how they work. I see block diagrams where people put either a 1 or a -1 into a mixer with a signal applied to it and they get PSK out but I can't quite come up with a design that works. I've looked at the gilbert cell... is this a good method for PSK or is there a name of a circuit you guys can refer me too to get PSK???
Thanks
