A system for processing a signal s(t) from a sensor to recover sensed signal information within the bandwidth of the summation signal, wherein the signal s(t) includes a sensed signal m(t) and an offset signal having a first frequency f1. The system comprises: a sampling device for sampling the signal s(t) at a second frequency f2 that is a multiple of the first frequency f1, to create a sequence of sampled values; and an averaging device for averaging the sequence of sampled values to provide a sequence of averaged sampled values indicative of the sensed signal m(t).
