Basic dumb question:

I read this in passing and am not sure I understood correctly. It
seemed to say that you can do image rejection with a quadrature
demodulator (by summing the outputs).

For example, feed 11MHz to an IQ demod running at 1MHz. The I & Q
outputs will each have 10MHz & 12MHz components in them. Sum the
outputs. One of the frequencies will phase-cancel, the other will add
constructively. Is this correct?

thx
