Digital phase selection system for signal multipliers

摘要

Phase adjustment techniques are disclosed for use with signal multipliers and the like. A system and method is disclosed for producing selected phase relationship product values in signals which are to be multiplied electronically. In one embodiment, a signal is modulated and then delayed in time by digital shifter prior to multiplication with a second signal. Techniques are disclosed for producing any desired time delay by digital shifter. A system for producing a phase lead in a modulated signal is also disclosed.
