✦ Synopsis
A statistical analysis of digital a posteriori Wiener filtering as applied to time averaging techniques for biological signals is presented. The authors show that when ap.w.f, is applied to the average signal hardly any effect can be expected, where as when applied to the individual responses, ap.w.f, improves the signal to noise ratio. The applied analysis leads to a simple test to check whether a prescribed frequency component is present.
