Abstract:
1. A device to generate a chaotic signal, comprising: a PN signal generator comprising a digital logic circuit and generating 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, the PN signal generator comprising a digital logic circuit, including N (N being a positive number) D-flip flops and a gate unit, and generating a predetermined bit number (2 each of the D-flip flops including an even number of inverters and switches and, in accordance with an applied sine-wave signal, outputting an input signal without phase inversion.
