1. A method for extracting values representative of modulation signal components from a modulated signal, the modulated signal containing a modulation signal, the method comprising:
defining a periodic time segment sequence having at least four ordered time segments and acquiring multiple sets of signal values from the modulated signal, for each signal value, acquiring, as the signal value, a difference in the modulated signal during each of two of the ordered time segments, the two ordered time segments differing in their order within the sequence by half of the number of ordered time segments in the sequence, each set acquired over multiple repetitions of the periodic time segment sequence, each set acquired during different ordered time segments than each other set, each signal value representative of a modulation signal component. |
