SIGNAL OUTPUT APPARATUS, SIGNAL PROCESSING APPARATUS, AND SIGNAL PROCESSING METHOD

摘要

In accordance with an example embodiment, there is provided a device outputting a signal for controlling another peripheral target device, comprising: a target signal generation unit that generates a target signal for controlling the target device based on a specific frequency set within an audible frequency; a signal storage unit that stores a base signal having a frequency differently set from the specific frequency within the audible frequency; and a signal output unit that outputs the target signal and the base signal together during pre-set threshold time or longer.
