Abstract

A compensating method and apparatus is provided which collectively compensates for variations in a variety of characteristics in respective circuit portions of a signal processing circuit. A correction data generator is provided for generating correction value data for correction to be made for an output signal of the signal processing circuit, in order to compensate for variations in the characteristics of the at least one circuit portion. Also, a compensator is connected to receive an output signal from the signal processing circuit as well as to receive the correction value data from the correction data generating means, for correcting the output signal in accordance with the respective correction value data corresponding to the at least one circuit portion to generate a compensated output signal.
