Abstract
Detection output from a detection circuitis converted to digital detection data Dand supplied to an AGC circuit AGCC and a noise clamping circuit NCC that are formed by digital circuits. In the AGC circuit AGCC, a digital low pass filtergenerates DC voltage data Dfrom the detection data D. A digital dividerperforms division of the DC voltage data Dby the reference detection level data Dindicating the detection data level. A digital multiplier multiplies the division results Dby the detection data Dto generate multiplication data Dthat is constant irrespective of a variation in the detection data D. In the noise clamping circuit NCC, a digital comparatorcompares the size of the preset voltage data Dand that of the multiplication data D. A selector circuitselectively outputs preset voltage data Dor multiplication data Dto generate signal wave data D.
