Abstract
A digital differential amplification control device includes: digital data generator for differential amplification control; differential controller for transmitting separately an A-phase signal which is a rectangular wave transmitted from the data generator, and a B-phase signal that is an inverted A-phase signal; and corrector for correcting at least one of the A-phase signal and the B-phase signal so that no cross point of the A-phase signal and the B-phase signal is present.

A digital differential amplification control device, comprising:
- digital data generator for differential amplification control;
- differential controller for transmitting separately an A-phase signal which is a rectangular wave transmitted from the data generator, and a B-phase signal that is an inverted A-phase signal;
- and
- corrector for generating a corrected waveform of at least one of the A-phase signal and the B-phase signal based on a clock signal for correction so that no cross point of the A-phase signal and the B-phase signal is present.
