Impedance is an inherent property that represents the relation between the excitation and motion of a system. It is not only gives the frequency characteristics of the system but also help us to understand an interaction with the other systems. If the impedance to be described is not with respect to a point but to a certain area, modal impedance must be used. However, it is highly dependent on modal functions and it is needed to know all information on the modal impedance to understand the whole characteristics. In this paper, two new types of impedances are introduced: the first and second kinds of total impedances. Their definitions certainly convey the implication that their properties are similar to the conventional impedance. With some limit checks and the simulations of several simple systems, we found that they are useful to describe the frequency characteristics of systems.
