Abstract
Provided is a device for generating a chaotic signal comprising a PN signal generator that is composed of a digital logic circuit and generates a digital pseudo random signal with a predetermined frequency; a voltage control that generates a clock signal with a predetermined frequency; a mixer that mixes the pseudo random signal and the clock signal so as to generate a chaotic signal to output; and a band-pass filter that filters the chaotic signal, output from the mixer, into a chaotic signal of a desired band and then outputs the filtered signal.
