Title: Innovations of Pierre Jaffre
Introduction
Pierre Jaffre is a notable inventor based in Lannion, France. He has made significant contributions to the field of synchronous digital transmission systems. With a total of three patents to his name, Jaffre's work has had a lasting impact on data transmission technologies.
Latest Patents
One of Jaffre's latest patents is a "Detector logic circuit for a synchronous transmission system for data." This invention involves a detector logic circuit that restores the value 0 or ±1 of a ternary symbol converted into a signal on five levels. The circuit employs binary logic circuits and is connected to a comparator that delivers a value representing the receive level through four binary signals. The circuit effectively delivers the values of the ternary symbols detected in the form of two binary components, which are stored for the duration of a symbol by two flip-flops.
Another significant patent is the "Synchronous digital cable transmission system." This system comprises a transmitting terminal, intermediate regenerative repeaters, and a receiving terminal. The transmitting terminal includes a data scrambler and a 6B/4T type binary-ternary line coder. The receiving terminal features a receive signal shaping and filtering unit, along with a logic device for decrypting binary symbol superpositions. This invention enhances the efficiency and reliability of data transmission.
