Non-linear characteristic estimation device and non-linear characteristic estimation method

摘要

Embodiments of the present disclosure provide an estimation apparatus and method for a nonlinear characteristic, which may simply and quickly estimate the nonlinear characteristic of a system to be measured by calculating parameters of the nonlinear model of the system to be measured according to the fundamental power and harmonic power of output signals of the system to be measured on at least two frequency spots obtained through measurement, with the accuracy of the result of estimation being relatively high.
