Abstract

"Peripheral blood pulse monitors are highly susceptible to noise-artifact-- in their present stage of development. The purpose of this thesis is to demonstrate a feasible means for filtering the artifact, using existing monitors. Since no peripheral pulse monitor (transducer) was available for experimentation, a simulated test input was devised with frequency variations from JO cycles/minute to 1.50 cycles/minute.

The filtering circuit predicts the time location of each input pulse. The location of the prediction is governed by the accuracy of the preceding prediction. This is controlled by an R-C timing circuit with a Schmitt Trigger and relay.

From the data obtained, it is estimated that at least 50% of the artifact will always be filtered. This is a conservative minimum however, and for low density artifact the percentage eliminated is increased as high as 90%"--Abstract, p. ii
