Abstract
PURPOSE:To obtain a code converting system which is capable of reducing the number of digital codes. CONSTITUTION:An analog wave 1 is A/D-converted at a sampling point 4, and its digital values are shown by ''3'' in the ascending order. When the uppermost digits of the digital values shown by ''3'' are seen in the ascending order, 5 pieces of ''0'' and 15 pieces of ''1'' are arranged, and in the next digits, 3 pieces of ''0'' and 4 pieces of ''1'' are arranged. According to the decimal notation, they are shown as 5-15-3-4-10-3-2-2-2-2-8-2-3-2-1-1-2-2-5-2-2-1-2-1-1-3-5-4-1-1-2-1-1. When they are counted by 13 bit binary notation, maximum 65,556 bits can be counted, therefore, they are considered to be decimal numbers consisting of 7 groups of (51534), (10322), (22823), (21122), (52212), (11354) and (11211). Therefore, the number of all bits converted to 13 bits is 13X7=91 bits, and becomes smaller than 100 bits being the number of all bits of binary numbers shown by 3 in the figure.
