Title:
波形発生器、波形整形器、及び試験装置
Document Type and Number:
Japanese Patent JP4732007
Kind Code:
B2
Abstract:
There is provided a waveform generator that generates a waveform. The waveform generator includes: a lamp waveform generating section that generates a lamp wave of which a signal value linearly changes for a predetermined period; a square wave generating section that generates a square wave of which pulse width is generally equivalent to the predetermined period; a waveform adding section that generally accords a timing at which a signal value in the lamp wave begins to be changed and a timing at a leading edge of the square wave, to add the lamp wave and the square wave; and a low-pass filter that removes a predetermined frequency band component from a waveform output from the waveform adding section.
