An improved method of weak signal erasometry based on Duffing oscillator
This paper is aimed at improving the previous experiments of duffing oscillator detecting weak signals. The influence of phase transition direction, signal phase, frequency and amplitude on Duffing system is analyzed and a new method for detecting weak signal by Duffing Oscillator is proposed. This method detects weak signals by the way of reverse detection, and calculates the threshold through Poincare section, so that the detection is more accurate.
