摘要： In a chaotic signal generator, a first signal generator generates a first signal. The first signal includes a first fundamental wave having a preset first frequency and a plurality of harmonic waves of the first fundamental wave. A second signal generator generates a second signal. The second signal includes a second fundamental wave having a preset second frequency and a plurality of harmonic waves of the second fundamental wave. Also, a mixer mixes the first signal from the first signal generator with the second signal from the second signal generator to generate a chaotic signal having a sum frequency of the first and second signals and the harmonic waves of the first and second signals. A filter passes a signal of a preset band out of the chaotic signal from the mixer.
