The statistical properties of a biological signal intermittently obscured by a relatively independent biological process are estimated by noting the time intervals during which the obscuring process is occurring. From the time intervals, a windowing function is constructed which makes a transition from one towards zero as the process obscures the signal and a transition towards one as the process ...
