The enhanced ac Josephson effect is studied based on an analog simulation when the junction is driven by an rf-signal source. On the basis of the resistively shunted Josephson junction model driven by a pulse train current, larger rf-induced current step-heights in the current-voltage characteristics were obtained in comparison with those obtained by a monochromatic sinusoidal drive. This result is considered to be originated by the harmonics of the rf-signal. In addition, the maximum value of the step-height is independent on the step number.
