Abstract : The distinctive hiss of radio 'noise' is familiar to all of us old enough to have listened to vintage a.m. radio shows and certainly to all those personnel who ever tried to 'pull in' a weak signal during a tour in military communications. Indeed, virtually since the birth of the telephone and radio and extending to today's sophisticated telecommunications designs, engineers have devoted prodigious efforts to eliminating or minimizing the effects of noise. In consequence, an entire discipline, known as linear filter theory, has evolved and is familiar to every electrical engineering and/or communications student, usually as one or a set of rather rigorous courses. By contrast, this paper is concerned with a nonlinear filtering process known as Stochastic Resonance (SR), research on which has been supported by the Physics Division of the Office of Naval Research (ONR) for several years and more recently by the Cognitive and Neural Sciences Division of the ONR.
