| Abstract: | A new method of chaotic measurement with resistor based on DSP is presented,and will be applied to measure the tiny change of resistor sensor,the new chaotic measurement system has better linearity and less error than old one,it is still very available when some components are low precise in measurement circuits,and circuits noise is reduced greatly as well,the experiment results based on new method are given just for comparing with other method,it is clear that the new method will have very good future in application. |
