| 摘要 | A device for translating a multibit input code into a desired multibit output code including a double-ended decoding circuit which converts the signals representing an input character into a single signal and apparatus which encodes this single signal into the signals representing a corresponding output character. | ||||||
| 权利要求 | 1. An electronic code converter for translating a set of input characters of a first code into a set of output characters of a second code, each of said input characters being represented by a plurality of input signals, said input signals being high or low level and being separated into first and second groups, various combinations of signal levels of said first group being defined as legal, a first group junction associated with each legal combination of signal levels of said first group, electrical current source means and electrical logic means, said logic means directing current from said current source means only to a selected first group junction associated with an input character to be translated, various combinations of signal levels of said second group being defined as legal, a second group junction associated with each legal combination of signal levels of said second group, a separate conductor connecting each first group junction with each second group junction, each conductor being associated with an input character, each of said output characters being represented by a plurality of output signals being high or low level, a core means for each output signal, each of said conductors being inductively linked with a predetermined combination of said core means, induction in a core means from current in a conductor producing an output signal of one level and the absence of induction in a core means producing an output signal of the opposite level, said logic means providing a current sink only at a selected second group junction associated with said input character to be translated thereby permitting the conductor associated with such character to carry current from said selected first group junction to said selected second group junction to produce an output signal level at each of said core means to represent an output character corresponding to said input character to be translated. 2. An electronic code converter for translating legal Hollerith code input characters into a set of output characters of a second code, each of said input characters being represented by a field group of signals and a digit group of signals, said signals each being high or low level, a junction of a first group associated with each legal combination of signal levels of said field group, and a junction of a second group associated with each legal combination of signal levels of said digit group, electrical current source means and electrical logic means, said logic means directing current from said current source means only to a selected junction of one of said groups associated with an input character to be translated and providing a current sink only at a selected junction of the other group associated with said input character to be translated, a separate conductor connecting each first group junction with each second group junction, each conductor being associated with a Hollerith character, each of said output characters being represented by a plurality of output signals being high or low level, a core means for each output signal, each of said conductors being inductively linked with a predetermined combination of said core means, inDuction in a core means from current in a conductor producing an output signal of one level and the absence of induction in a core means producing an output signal of the opposite level, the conductor associated with said input character to be translated carrying current between said selected junctions thereby producing an output character corresponding to said input character. 3. An electronic code converter as set forth in claim 2 wherein said logic means includes a logic tree which selects said junction of said first group. 4. An electronic code converter as set forth in claim 2 wherein said logic means includes a plurality of integrated circuit gates which select said junction of said second group. 5. An electronic code converter as set forth in claim 4 wherein means are provided to supply a strobe signal, and said selecting gates are controlled by said strobe signal. 6. An electronic code converter as set forth in claim 2 wherein each of said core means includes a transformer core, said conductors are selectively threaded through predetermined combinations of said transformer cores, each of said transformer cores having an associated secondary winding, current in a conductor passing through a transformer core inducing current in the associated secondary winding resulting in an output signal of one level, current in a conductor not passing through a transformer core not inducing current in its associated secondary winding and resulting in an output signal of the opposite level. 7. An electronic code converter as set forth in claim 6 wherein a latching circuit is provided for each core means, each latching circuit providing a high or low level output signal. 8. An electronic code converter as set forth in claim 7 wherein reset means are provided, said reset means driving the output of all of said latch circuits to a common signal level at the end of a cycle of character translation. |
