In this study, a diode rectifier circuit of impact oscillator is presented. The commercial software of MultiSim is used to simulate the circuit, where the time series analysis is performed. For varying the driving frequency, a fixed harmonic input voltage can generate a periodic or non-periodic impact oscillation through the proposed circuits. The phenomena of bifurcation are also observed. Finally, the motion behaviors of electronic impact oscillator showed an agreement with previous study of mechanical impact system.
