The Correction of Signals Distorted by Linear Apparatus
C. Peter Flynn · Proceedings of the Physical Society · 1961
In a previous paper by Flynn and Seymour a technique was developed whereby a type of distortion produced by linear apparatus could be corrected rapidly and efficiently to obtain a `true' output signal. The distortion considered was not the most general linear distortion, and several cases of practical importance were therefore excluded. In the present paper, the general linear distortion is examined and equations are developed which permit the rapid correction of distorted output signals into those to be anticipated from the use of ideal apparatus. The procedure is illustrated by means of an example. The accuracy of the corrected signals is then discussed, and it is shown that in some apparatus, as for instance, the magnetic resonance spectrometer, predictable optimum conditions occur under which the form of the true output signal may best be determined.
