Abstract

This translator can translate data of an A and a B code into a B and an A code, respectively. This translator consists of a known translator A to B translating data of an A code into a B code and which is associated with an input and an output register. For the translation of data of an A code into a B code, the A code data to be translated are entered into the input register and are transferred to translator A to B where it is translated and subsequently fed to the output register. For the translation of data of a B code into an A code, the only additional means required are a compare circuit and a connected character generator which applies its output pulses to translator A to B and which comprises a second output for code A.

Code Translator

This translator can translate data of an A and a B code into a B and an A code, respectively. This translator consists of a known translator A to B translating data of an A code into a B code and which is associated with an input and an output register. For the translation of data of an A code into a B code, the A code data to be translated are entered into the input register and are transferred to translator A to B where it is translated and subsequently fed to the output register. For the translation of data of a B code into an A code, the only additional means required are a compare circuit and a connected character generator which applies its output pulses to translator A to B and which comprises a second output for code A. For translating a B code character into the A code, the character is initially entered into the input register. When the character to be translated is in the input register, the character generator which can be a counter or shift register is caused by clock pulses, not shown, to generate characters, applying them to the input of translator A to B.

This measure results in B code characters being generated on the output of the translator. If the B code character in the input register complies with the B code character in the output register, the compare circuit supplies a parity signal on its output, thus blocking the character generator. The character available on the output of the character generator is in the required code...
