PURPOSE:To obtain assuredly a fixed detection level with a small number of bits by providing a circuit to supply the value of prescribed times as high as the detection level to the initial input. CONSTITUTION:An initialization cicuit 4 is added to a conventional digital integrator to supply the value of (m) times as high as the detection level as the initialization. The value of output signal Eo, the output of a delay circuit 2 and the output of a multiplier circuit 3 are all cleared to zero at first. Then the initialization value is supplied to the circuit 4, and the initialization value is continuously fed to the input voltage Ei. When the initialization value is set at the value of (m) times as high as the detection level SL, the number of bits can be reduced compared with the conventional value to obtain the detection level. |
