The Whole Frequency Detection Method of Weak Sine Signal

摘要：

Based on the immunity to the white noise and the period interfere signal, employing the locking function of the modified Chuas circuit, the detected signal is used as a part of modulation signal of variable capacitance diode. This will be able to control left and right jump of single scroll attractor in the control system and implement to detect the weak sine signal. By numerical experiments, we find the period relationship between modulation signal frequency and system phase change. This will be able to detect the whole frequency signal detection.
