Data code conversion for remote signalling and control systems
Abstract
Abstract A MESSAGE IS FORMED BY THE OUTPUT PULSES SUCCESSIVELY DELIVERED BY A CHAIN OF (M+1) MONOSTABLE MULTIVIBRATORS, THE FIRST ONE DELIVERING A SYNCHRONIZING PULSE OF DURATION 3T, THE OTHER M ONES (THE TIME CONSTANT OF WHICH IS MADE EQUAL TO T OR 3T/2 ACCORDING TO THE BINARY SIGNAL TO BE TRANSMITTED) DELIVERING THE INFORMATION PULSES. WHEN A MESSAGE HAS BEEN TRANSMITTED A FEED BACK LOOP TRIGGERS THE TRANSMISSION OF A FURTHER MESSAGE. THE DECODER COMPRISES A SYNCHRONIZING PULSE DETECTOR AND A CHAIN OF M BISTABLE MULTIVIBRATORS CONTROLLED BY THE RECEIVED SIGNALS TO RESTITUTE THE PULSE GENERATED IN THE CODER BY THE FIRST M MONOSTABLE MULTIVIBRATORS, AND M CIRCUITS FOR DETECTING THE DURATION OF THESE PULSES.
