Abstract
Reduction in signal intensity of a harmonic component included in an output of a delta-sigma modulator is suppressed. A signal processing device includes: a delta-sigma modulatorthat outputs a pulse signal; a first processorthat generates, from the pulse signal Poutputted from the delta-sigma modulator, a discontinuous pulse signal Pin which each of one-pulse sections in the pulse signal Phas a low level region on at least one of a rear end and a front end of the one-pulse section; and a second processor that generates a short-width pulse signal Phaving a pulse width shorter than a pulse width of the discontinuous pulse signal Pgenerated by the first processor
