Image forming apparatus, signal outputting apparatus and signal outputting method

摘要

An image forming apparatus includes a function unit to perform one or more functions of the image forming apparatus; and a control unit (200) to control the function unit to perform the functions of the image forming apparatus, wherein the control unit (200) includes: a first signal generator (210) to generate a first signal comprising a control signal to control the function unit; a second signal generator (220) to generate a second signal comprising a pulse signal with a predetermined high frequency; a synthesizer (230) to generate a third signal by synthesizing the first signal and the second signal during an edge period of the first signal; and an outputter (240) to output the third signal.
