Title: Improvements in or relating to electric circuit arrangements
IPC: G06F11/16
Filed: 1965-04-20
Abstract: 1,081,543. Data transmission. SIEMENS A.G. April 20, 1965 [April 21, 1964], No. 16627/65. Heading H4P. To reduce the possibility of system failure or error the receiving arrangement in a data trans. mission system comprises a number of channels carrying identical data. From an exchange identical data is received on m input channels, each channel feeding a corresponding n bit core or transistor store. The parallel data is read from all the stores simultaneously, and each of the m x n bits so derived feeds a corresponding pair of channels. The channels of each pair of channels are connected to individual transformers corresponding to like numbered bit positions in the stores. Each group of n transformers passes a parallel signal to an individual output device. Thus if any input channel or either output device fails the correct data still passes to the other output device. The transformers are arranged to act as differentiators so that if an associated transistor fails the resultant D.C. voltage has no effect on the transformer. Diodes between the transistor and the transformer prevent spurious pulses in the secondary from harming the transistor, a Zener diode suppresses highamplitude spurious voltages, and biased diodes suppress low-amplitude spurious voltages from the stores. The transistors are fed with D.C. individually via the transformers.
