Abstract
PURPOSE: To simplify adjustments in manufacture and maintenance processes by stabilizing operating states by varying a mixing ratio of input signals in accordance with a digital signal.
CONSTITUTION: Two input terminals 24 and 25 are provided and signals (ein1) and (ein2) are supplied from different signal sources 20 and 21 to those input terminals; and switches S1∼S8 which alternate and set input terminals 24 and 25 are provided and the output signal of each switch is supplied to input terminals 24 and 25, thereby constituting lattice-shaped resistance circuit network 26. Then, a mixing ratio of input signals (ein1) and (ein2) is varied according to a digital signal. Consequently, adjustments in manufacture and maintenance operations can be simplified in a stable operation state.
