Abstract:
A method of processing a signal, comprising:inputting a signal to a circuit, wherein said circuit comprises one or more capacitive elements and one or more resistive elements, wherein each capacitive element comprises a charge/discharge current, wherein said circuit has an effective RC time constant dependent on the magnitudes of the one or more capacitive elements and the one or more resistive elements; and interrupting at least one of said one or more capacitive element's change/discharge current in a periodic manner, wherein said at least one of said one or more capacitive element's charge/discharge current is uninterrupted for &tgr; seconds within each period T and interrupted for T-&tgr; seconds within each period T resulting in a duty-cycle of k=&tgr;/T for said at least one of said one or more capacitive element's charge/discharge current, wherein the interruption of said at least one of said one or more capacitive element's charge/discharge current in a periodic manner modifies the circuit's effective RC time constant by 1/k.
