Zusammenfassung:	PROBLEM TO BE SOLVED: To solve such a problem that a period signal generator is required, the period signal generator correcting attenuation of amplitude due to amplitude characteristics of a filter and outputting a period signal changing a frequency thereof over a wide band.SOLUTION: In a period signal generator, signal frequency information is input, and a period signal corresponding to the signal frequency information is output through a filter circuit. The period signal generator includes: an amplitude correction section for outputting a ratio value to correct attenuation of amplitude due to amplitude characteristics of the filter circuit; and a multiplier for multiplying the period signal by an output of the amplitude correction section. 【課題】フィルタの振幅特性による振幅の減衰を補正した、広帯域にわたり周波数が変化する周期信号を出力する周期信号発生装置が必要とされている。【解決手段】周期信号発生装置は、信号周波数情報を入力とし、信号周波数情報に対応した周期信号を、フィルタ回路を介して出力する周期信号発生装置であって、フィルタ回路の振幅特性による振幅の減衰を補正する比率値を出力する振幅補正部、周期信号に振幅補正部の出力を乗算する乗算器を備える。【選択図】図１
