A study on duffing oscillator s ability on detecting disappearance of the detected weak signal

After the successful use of duffing oscillator in weak signal detection, many researches are done on this subject. Most of these studies only analyze the efficiency of duffing oscillator on detecting the existence of weak signal and they ignore to study duffing oscillator’s ability on detecting the loss of signal that was already detected. Considering this, we are going to analyze this ignored issue. In this paper we introduce two methods to add this ability to duffing oscillator.
