The main purpose of the paper is to investigate whether human control characteristics are invaiable, even though wave forms as target vary. Step waves or sinusoidal waves (0.51-4.47cps) were tracked by 6 subjects with an effort to nullify the error. Amounts of training in step waves and sinusoidal waves as targets are matched according to experimental design. Average response curves are computed from both of step response and sinusoidal responses in accordance with K. Izawa's method (1964), and vece versa. Consequently, in both of transient characteristics and frequency characteristics, the sinusoidal response is quicker than the step response. Human control characteristics are relatively invariable, even though wave forms vary. In transient characteristics, the step response transformed from sinusoidal response is quicker than the original step response, but the former is not so stable as the latter. In frequency characteristics, however, the transformed sinusoidal response is more monotonic than the original sinusoidal response.
