A signal processing device includes a start time obtaining part that obtains a start time when a predetermined process is started in response to an interrupt request associated with a valid edge of a pulse input signal, an edge occurrence time obtaining part that obtains a time of occurrence of the valid edge of the pulse input signal after the start time of the predetermined process is obtained, and a processing part that selectively performs a process based on a time relationship between the start time of the predetermined process and the time of occurrence of the valid edge.
