Abstract
An electronic equipment manufacturer has been bearing the burden to adjust variations in characteristics of semiconductor integrated circuits according to a conventional art. The device and the method of this invention include a microcomputer, signal processing circuit which processes an input signal accordingly to a control signal from the microcomputer and provides an output signal and a memory which stores adjustment values to adjust changes in signal characteristics due to variations in manufacturing of elements composing the signal processing unit. The microcomputer adjusts the changes in the signal characteristics of the signal processing circuit according to the adjustment values stored in the memory.
