PURPOSE:To obtain an effective secondary variable and function generating circuit, by deriving desirable control voltage experimentally in advance, against two kinds of photoelectric converting output level, and operating the desirable control voltage when an optional photoelectric converting output is provided. CONSTITUTION:An absolute value circuit ABS for converting an input to an absolute value and deriving it is provided, a comparing circuit outputs a larger one of two inputs, a code deciding circuit discriminates a triangular area containing a deciding condition, outputs a coefficient value against an experimental value, and at most, three code deciding circuits generate an output simultaneously, each output multiplied by the experimental value is added, and desirable control voltage is derived. In this way, the control can be executed exactly, and an effective secondary variable and function generating circuit can be obtained. |
