A CIRCUIT FORMS THE COMPLEMENT OF THE SIGNALS. AN ADDER RECEIVES THE ADDRESS TO BE TRANSLATED AND COMBINES THE ADDRESS WITH THE PARAMETER SIGNALS OR THE COMPLEMENT OF THE PARAMETER SIGNALS, THEREBY FORMING A CODED RESULT SIGNAL. THE ADDER ALSO COMBINES THE RESULTS FORMED THEREBY WITH THE PARAMETER SIGNALS OR THE COMPLEMENT OF THE PARAMETER SIGNALS. A COUNTER IS PROVIDED FOR EACH OF A PLURALITY OF THE ADDRESS PARTS AND COUNTS THE NUMBER OF TIMES THE CORRESPONDING PARAMETER COMPLEMENT IS COMBINED WITH THE ADDRESS OR THE RESULT SIGNALS BEFORE THE CODED RESULT SIGNALS BECOME LESS THAN ZERO. THE STATE OF THE COUNTERS AND THE RESULT AFTER ALL PARAMETER SIGNALS HAVE BEEN COMBINED, REPRESENT THE TRANSDUCER SELECTION AND ANGULAR POSITION PARTS OF THE TRANSLATED ADDRESS.
