Abstract
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).

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