Abstract
PURPOSE: To lower the price of digital control means, by obtaining digital value carrying out comparative A-D converting in sequence, using twice DA converter having number of bits lell than required bits.
CONSTITUTION: Central processoes CPU gives prescribed operation to the signal converted into digital value from the signal of multiplexorl, being used to output the output signal V at the operating end through D/A converter D A multiplexor 2. Signal selectted with multiplexor lis compared with signal which contents of register in the I/O port is converted, contents of register is changed by proper method until it meets. In the xase of not meeting, its difference is held to condenser CE, furthermore similar operation is carried out with amplifier OP and other register, operation will be started taking data combined with both registers for input signal
