Active Low Pass Filter Design Based on Chaos Theory

Article Preview

Abstract:

The circuit in this paper is an effective solution to interference and noise of input signal during data acquisition and the circuit designed is based on an active low pass circuit with output frequency from 0~100Hz. The low pass circuit consisted mainly of an OPAMP TL084. Chaos theory is applied in this active nonlinear filter.The designed circuit is analysed by Matlab simulation software and the simulation results show the method can effectively improve effects of the filtering circuit.
