Claim 1
Independent Claim
120 words
A DEVICE FOR CONVERSION BETWEEN AN ANALOGUE SIGNAL AND A DIGITAL SIGNAL WITH NON-LINEAR QUANTIZATION COMPRISING A PLURALITY OF INPUT TERMINALS FOR RECEIVING DIGIT CODES COMPOSING A CODEWORD, RESPECTIVELY; LOGICAL OPERATION CIRCUITS CONNECTED TO SAID INPUT TERMINALS FOR PERFORMING LOGICAL OPERATION FOR EACH PREDETERMINED COMBINATION OF AT LEAST ONE OF SAID DIGIT CODES TO PRODUCE LOGICAL OUTPUT CODES; A PLURALITY OF STANDARD POWER SOURCES CONNECTED TO SAID INPUT TERMINALS AND SAID LOGICAL OPERATION CIRCUITS, AND RESPECTIVELY CONTROLLED BY SAID DIGIT CODES AND SAID LOGICAL OUTPUT CODES TO RESPECTIVELY GENERATE ELECTRIC QUANTITIES IN RESPONSE THERETO, AND IN ACCORDANCE WITH A PREDETERMINED LAW; AND MEANS CONNECTED TO SAID STANDARD POWER SOURCES TO COMBINE SAID ELECTRIC QUANTITIES TO DELIVER THE DESIRED DECODED OUTPUT.
