BIFURCATION AND CHAOTIC PHENOMENA IN A LOGISTIC MAP SYSTEM IN CONDITION OF FINITE WORD-LENGTH

摘要

This paper studies a finite word-length logistic map system. Under the condition of the limitation of word length, remarkably complex phenomena such as sub-harmonics, bifurcation and chaotic behaviors have been investigated through computer simulation. The round-off noise caused by the system is analyzed. The Cut-and-Try Method is adopted to locate the value of u in period 5. Power spectrums with specific μ are drawn.
