FREQUENCY MULTIPLICATION CIRCUIT OF SYNCHRONIZED CHAOS SIGNAL

摘要

PURPOSE: A frequency multiplication circuit of synchronized chaos signal is provided to be used for modulating or demodulating a frequency or a frequency shift keying. CONSTITUTION: Two frequency multiplication circuits of synchronized chaos signal are connected each other by a coupled resister. As resisters(time invariant value elements), operation amplifiers and powers are identically built in those two frequency multiplication circuits, two chaotic trajectories generated from the circuits have the same initial characteristics and movements. In addition, one chaotic trajectory velocity is proportional to the other chaos trajectory velocity n-times or 1/n-times. Consequently, a chaotic frequency shift keying can easily modulated or demodulated, because the chaos signals in which only frequencies are multiplied are generated.
