摘要
文章基于混沌理论提出了一种性能优良的方波信号混沌测量法,在对该方法的测量原理及噪声影响等问题进行严格理论分析的基础上,用自制的宽带超低噪声前置放大器,首次实现了0 1nV微弱方波信号的测量,测量方差优于0.6×10-3。
Based on chaotic theory,an effective chaotic detecting method for squarewave signal on the basis of strict analysis of measurement principles and the influence of some problems such as noise is presented. Using homemade broadband verylow noise preamplifier, 01 nV squarewave signal measurement has been realized and measurement variance is better than 0.6×10-3.
