PURPOSE:To use a decision signal as an initializing input for a digital computer by increasing an integral output with a fixed time constant when the decision signal is generated while decreasing it by a feedback resistance with the fixed time constant when not. CONSTITUTION:In accordance with a previously-fixed control program, digital computer 100 repeats arithmetic processing and direct-current reproducing device 191 integrates the repetitive pulse by using a rectifier and accumulator. When this integral signal decreases lower than a fixed threshold value, decision circuit 193 generates a decision signal and in this case, the integral output of direct-current reproducing device 191 is increased with a fixed time constant. When no decision signal is generated, the integral output is decreased by feedback resistance 196 with the fixed time constant. Consequently, the decision signal of circuit 193 can be inputted as an initializing signal to computer 100. |
