Abstract

　ＰＬＬループを備えた位相同期発振器の誤差検出手段は、電圧制御発振器から基準周波数変調信号が出力された場合の前記位相比較器から出力される基準位相誤差信号と、位相比較器から実際に出力される位相誤差信号との差分を求め、さらに当該差分の変化率に基づいて電圧制御発振器からの周波数変調信号の周波数誤差を検出する。位相同期発振器の補正手段は、周波数変調信号の所定区間の周波数誤差の平均値を算出し、平均値が０となるように補正することにより周波数変調信号の中心周波数を補正し、周波数変調信号の１周期内における少なくとも２つの周波数誤差の比較に基づいて、制御ステップ毎の制御電圧の変化率を変化させることにより、周波数変調信号の周波数偏移を補正する。
