WAVEFORM CONVERTING APPARATUS, WAVEFORM CONVERTING METHOD TEST APPARATUS AND TEST METHOD

摘要

An waveform converting apparatus is provided. The waveform converting apparatus includes: an amplitude converting section that multiplies an amplitude component of the input signal more than a predetermined amplitude value by a conversion coefficient which gradually decreases in accordance with the amplitude value; and a filter that removes a frequency component out of the frequency band of the input signal among the frequency components of the signal generated by the amplitude converting section.
