Title: Duplex data transmission system - has only one AC carrier for both terminals and has rectifiers switched in to select positive or negative half-waves
Inventor: AGRICOLA MANFRED DIPL ING
IPC: H04L5/04
Filed: 1976-10-01
Abstract: The data transmission system switches between the positive and negative half waves of an ac voltage using appropriately poled rectifiers. Data can be exchanged simultaneously in both directions between data terminals. Each of the two data terminals involved has switchable rectifiers that can be switched to the channels linking the two terminals. The rectifiers of one terminal transmit the positive half waves to the second terminal whilst the rectifiers of the second terminal transmit the negative half waves of the first. Further sets of diodes are used to register the data. Only one ac source is needed and provides the data carrier for both terminals.
