Hi,
I have a question that seems simple but is surrounding my mind. From my understanding, a signal can be represented by its in-phase and quadrature componentes (which are low pass signals). The relationship is the following
A(t)*cos(wt +phi(t) ) = si(t) * cos(wt) - sq(t) * sin(wt) , being si(t) and sq(t) the associated I and Q signals respectively.
So, imagine I have just cos(wt), does it means that si(t) is always = 1? I.e, samples IQ IQ IQ IQ IQ IQ would be
And what about sin(wt), would be sq(t) = -1 amd si(t) = 1, i.e. samples IQ IQ IQ IQ IQ IQ would be 0-1 0-1 0-1....
Regards,
