ABSTRACT:
A network for separating an article-detect signal into a number of parts corresponding to the number of articles randomly disposed in next-abutting relationship is characterized by a circuit arrangement adapted to sample and hold a predetermined percentage of the peak magnitude of a characteristic signal representative of each article, a comparator for comparing the instantaneous value of the characteristic signal with the predetermined peak and for generating an enabling signal when the instantaneous characteristic signal falls below the predetermined percentage, and a timer responsive to the enabling signal to interrupt the article-detect signal for a predetermined time interval after a predetermined time delay.
