Abstract
The electrical response of a transducer contains a data-providing signal or signals superimposed on an unwanted time-variable background signal which is independent of the data-providing signal or signals. A system processing the transducer response utilizes an electronically stored digital simulation of the background components whereby combination of the transducer output with the digital simulation, after digital to analogue conversion of the latter, substantially frees the transducer output of the background component to facilitate detection of the data-providing signals.
