Abstract
A signal processing device includes a detecting part that detects intensity of an input signal, a timer part that includes a time constant circuit and measures time based on a time constant of the time constant circuit, and a determination circuit that counts the number of times of switching of the input signal detected by the detecting part within the time measured by the time constant circuit.
