Phase synchronized triggering: a method for coherent noise elimination in evoked potential recording.
Abstract
While standard evoked potential recording techniques reliably attenuate gaussian and white noise, they are not similarly effective in reducing coherent noise such as that induced by power lines. We have presented a technique that will effectively eliminate coherent noise. This technique is especially appealing for clinical settings where 60 Hz artifact and a few discrete frequencies are most troublesome, such as in operating rooms or intensive care units. An added advantage of the technique is that it is especially well suited to applications requiring small sample sizes.
