ABSTRACT:
A frequency characteristics compensation method that can be applied to various waveforms (strategies). When determining the amount of frequency compensation, a deteriorated part by frequency characteristics is compensated for with respect to the difference between the pulse power to be compensated and the power level immediately before it. The present invention can also be applied to variations in the performance, aged deterioration, and temperature characteristics.
