Abstract
Binary coded decimal continuously varying data is monitored by comparing the value of the least significant bit for each digit of each received digital word to the same bit value of the immediately preceding digital word and generating a pulse each time that that value changes and providing a composite pulse equal to the sum of the amplitudes of all coincident pulses to afford an easily readable visual display of the data.
Claims12
Apparatus responsive to value changes in binary coded decimal digital words representative of continuously varying data, comprising:
- means for receiving each digital word;
- a plurality of storage means connected to the output of said receiving means, there being a different one for each of the digits represented in each digital word, each having means for receiving and storing at its output the value of the least significant bit for its associated digit when enabled;
- means for enabling said storage means upon receipt of a new digital word, and
- a plurality of pulse generators, there being a different one for each of said storage means connected to its output for providing a pulse each time that its associated storage means output changes value irrespective of the direction of change.
A method for providing pulse responses to value changes in binary coded decimal digital words representative of continuously varying data, comprising:
- simultaneously comparing the least significant bit value for each digit represented in each received digital word to the same bit value of the immediately preceding digital word, and
- generating a pulse for each comparison of a bit value that has changed irrespective of the direction of change.
