Abstract :
We shall examine the real-time restoration of biomedical signals under additive noises. The observation system of nonstationary biomedical signals is described using a mathematical model, and several restoration filters that are composed of a series of such models are proposed. These filters restored band-suppressed approximations of the original signals in real-time. An optimum filter that accounts for restoration error and additive noise is proposed
