Abstract
Values representative of modulation signal components are extracted from a modulated signal. The modulated signal contains a modulation signal. A local clock signal is developed which correlates in time to the modulated signal and has a plurality of non-overlapping phase sectors per cycle. The modulated signal is accumulated into an accumulated value, separately for at least one phase sector of one cycle of the local clock signal. Each accumulated value is representative of a modulation signal component. The modulated signal accumulated is of an amount representative of the mathematical integral of the modulated signal during each phase sector of the local clock over which the modulated signal is accumulated.
