Abstract
ν σύστημα τηλεφωνικής μεταδόσεως του τύπου χρονικής κατανομής παρέχον διαπολικόν δειγματισμό και λήψιν σήματος ταυτοχρόνως επί αμφοτέρων των ακροδεκτών μόνον όταν η διέλευσης του σήματος είναι ταυτοχρόνως παρούσα επί αμφοτέρων των κατευθύνσεων με τον σκοπό όπως αφαιρεθώσι οι θόρυβοι λόγω φαινομένωνήχους χαρακτηριζόμενη εκ του ότι εν κύκλωμα Δ επίεκάστου ακροδέκτου εκτελεί σύγκρισιν μεταξύ της στάθμης των δειγμάτων σήματος εν μετάδοση και της αντιστοίχου στάθμης δειγμάτων σήματος εν λήψη, ίνααποκλείσει την ανίχνευση του εν μετάδοση δείγματος επί του αντιθέτου ακροδέκτου όταν τα ειρημένα δείγματα δημιουργούνται εκ της ανακλάσεως των αντιστοίχων εν λήψη σημάτων.
