  • Abstract
    The multichannel signal processor described provides an excellent capability for the detection of any kind of signal, on-line, with a SNR of 0.1 dB at a wide frequency range. This very efficient and inexpensive approach to improving the SNR by the processor wiUl reduce the need for other signal processing techniques. The processor´s reaction on an input signal and noise has been analyzed by a mathematical model. This effect is IMustrated by an in vivo noninvasive detection on a beat-by-beat basis of electrical activity of the His¿Purkinje system of the heart, and the detection of a pulse-like signal from a generator.
