More Information
Summary:A physiological event detector including apparatus for receiving and detecting an electrical signal corresponding to a physiological event. The apparatus produces a logic level output when the input signal meets both passband energy criteria and time duration criteria. The structure of the invention includes a filter for selecting the passband criteria and digital timing circuitry for determining how long the passband signal exceeds a minimum energy threshold.
