DIGITAL DIFFERENTIAL AMPLIFICATION CONTROL DEVICE

摘要

A digital differential amplification control device includes: digital data generation means (202) for differential amplification control; an A-phase signal which is a rectangular wave transmitted from the data generation means; differential control means (204) for transmitting this A-phase signal separately from a B-phase signal as an inverted A-phase signal; and correction means (214, 216) for correcting at least one of the A-phase signal and the B-phase signal so that no cross point between the A-phase signal and the B-phase signal is present.
