PURPOSE:To secure generation of the equi-probability emergence distribution signals in a simple way via the D/A converter plus the random number generator containing at least one logic code signal generator circuit which generates the signals of logic 1 and 0 at random and with the same probability. CONSTITUTION:Logic code signal generator circuit LCS1-LCS4 generate the signals of logic 1 and 0 at random and with the same probability at each time. And each logic code signal emerging at each of output terminals a1-a4 of the above mentioned logic code signal generator circuits is applied individually to logic code input terminals b1-b4 of D/A converter DAC. Then the signals of the voltage value distributing between two set voltage value emerge at random and with the same probability at each time and are then transmitted to output terminal 0 from converter DAC based on the signal conversion characteristics determined by the constitution of DAC. |
