ABSTRACT:
A method for storing compressed data indicative of an analog signal and reproducing that analog signal from the compressed data. The analog signal to be stored is superimposed on a rectangular coordinate system. An elementary interval is defined on the X-axis of an X-Y coordinate system for the selection of a first series of points, a second series of points (R.sub.1, R.sub.2, R.sub.3) is determined by establishing a threshold ratio between the chord (C.sub.1, C.sub.1 ') separating two non-consecutive points and the sum of the chords (C.sub.1, C.sub.2, C.sub.3 ; C.sub.1 ', C.sub.2 ', C.sub.3 ') separating each of the consecutive points within two non-consecutive points. An interval (N) between these two non-consecutive points is selected to correspond to the maximum ratio below this threshold. The analog signal is reconstituted by generating a signal having a curve that is plotted by establishing between each group of three non-consecutive points a parabola with respect to the axis of symmetry corresponding to the axis of the elementary intervals.
