ABSTRACT:
An apparatus for recognizing relative extrema in a dispersive digital data word sequence which includes relatively few, simple component elements specifically including a comparator which generates a positive or zero logic signal depending on the sign of the word comparison between two successive words, a counter operating within a limited numerical range for counting the comparator output signals upward or downward, and a threshold detector responding when a given counter status is exceeded or fallen short of for maximum or minimum indication, and which due to its structurally and operatively simple design ensures real-time processing of scattering data word sequences with a high word frequency, e.g., 500 MHz.
