Abstract

【課題】　　所定の周波数の高周波電波に乗ったノイズを抽出し、そのノイズの発生個数、発生時刻、ノイズの強度等からノイズの状態を観測し、ノイズ発生の原因となった事象を推測する。 【解決手段】　出力信号ＳＨＳを高周波増幅器ＡＭＰ3 により、また出力信号ＳＨＲは高周波側振幅低減手段を講じたＡＭＰ4 でそれぞれ第２次増幅を行う。この場合、ＡＭＰ4 は高周波領域のゲインが小さいので、その出力ＳＨＲ－2 は振幅が減少するが、高周波ノイズは搬送波ＳＨよりさらに周波数が高いので、ノイズＮｚＢの振幅はより一層小さくなる。他方の出力信号ＳＨＳは広帯域の増幅装置ＡＭＰ3 によりそのまま増幅され、その振幅をＳＨＲ－2 として揃えるように全域にわたっての振幅調整手段を通してＳＨＳ－2 とＳＨＲ－2 との幅を揃えてからもう一度両信号加算増幅手段により相互加算しかつ所定の敷居値を設定してノイズを抽出する。
