ABSTRACT:
An IC for generating various signals for television includes a switch circuit for selecting a signal to be monitored from the various signals and outputting the selected signal through an external terminal. A selection signal for selecting and outputting the signal to be monitored is supplied from a microcomputer to the IC. The microcomputer compares data contained in the signal selected and output from the IC with data which has been prepared in advance. Based on the comparison result, adjustment data used in generating a corresponding signal in the IC is renewed.
