Abstract
A system and a method for obtaining improved quality electrical signals generated anatomically. Included in the system are primary terminals suitable for implantation so as to pick up an anatomically generated primary signal comprising both a desired component derived from a primary tissue source and a noise component derived from an auxiliary tissue source directly adjacent to the primary source. Also included are auxiliary terminals suitable for implantation directly adjacent to the primary terminals so as to pick up an anatomically generated auxiliary signal derived from the auxiliary signal source. Electrical leads connect the primary and auxiliary terminals and an output circuit having a processor for differentially combining the primary and auxiliary signals. By obtaining and then differentially combining both the primary and auxiliary signals there is obtained a high quality output signal corresponding to the desired component of the primary signal.
