ABSTRACT:
The invention features furnishing a representation of the quadrature amplitude modulation of two input signals (e.g., U and V video signals) based on the phase of a reference signal (e.g., a color burst reference signal). The two input signals are scaled based on the phase of the reference signal, and the scaling is synchronized to the phase of the reference signal.
