Abstract
A multi-carrier measuring apparatus includes a multi-carrier generator for generating a multi-carrier signal composed of signals having plural frequencies and being orthogonal to each other, an output for inputting the multi-carrier signals to a object at the same time, and receiving the multi-carrier signals reflected on or passed through the object, a frequency characteristic measuring apparatus for measuring the characteristics for the respective frequencies of the object based on the received signal, and an indicator.
