The square wave response of a first-order circuit has an oscillatory nature. In this paper, from first giving simulations of first-order circuits with different duty cycles at different frequencies and then eliciting questions and conjectures, the square wave response of different cases is then unified and the response expressions are rigorously derived using mathematics, and the response characteristics are finally discussed and the square wave response characteristics of first-order circuits are named stable oscillations.
