The real and imaginary parts of baseband signals
are obtained from a real narrow–band signal by quadrature
mixing, i.e. by mixing with cosine and sine signals at the
narrow band’s selected center frequency. We address the
consequences of a delay between the outputs of the quadrature
mixer, which arise when digital samples of the quadrature
baseband signals are not synchronised, i.e. when ...
