Abstract
A signal output circuit includes a signal correction circuit, having a clock signal input thereto, which corrects the clock signal to output the corrected signal, and a waveform shaping circuit that shapes a signal from the signal correction circuit. In the clock signal, pulses having a pulse width τ capable of being represented by a length of a time are periodically arranged with a period T, and the pulse width τ and the period T satisfy a relation of τ/T≠0.5. The signal correction circuit attenuates a signal having a second frequency based on a time width of at least one of the pulse width τ and a pulse width T−τ, rather than a signal having a first frequency based on the period T.
