Abstract
Signals subject to amplitude variations, such as physiological signals, are detected when the amplitude thereof exceeds a threshold level, where the threshold level is made adaptive to both the amplitude and the rate of the signals so as to desensitize the detection process for artifacts, which occur sporadically, and to avoid the need for automatic gain control of the signals prior to detection.
