Abstract:
1. A signal processing channel for identifying events in an analog input signal, the signal processing channel comprising: an analog-to-digital converter programmed to convert the analog input signal to a digital waveform, wherein the analog input signal has a first signal and a second signal overlapping in time; and a digital processor programmed to analyze a segment of the digital waveform, the segment has the first signal and the second signal overlapping in time during a time window triggered by an event, the digital processor including a form parameter forecaster that provides forecasted form parameters based upon different superpositions of a first signal component and a second signal component, the digital processor identifying the first signal component in the time window based upon a set of form parameters derived from the segment of the digital waveform during the time window and the forecasted form parameters, wherein the different superpositions correspond to a plurality of different amounts of overlap of the first signal component and the second signal component and wherein the first signal and second signal are physiologic signals and the first signal component and second signal component are physiologic signal components.
