The delta function showing the existence of the echo is scarcely overlooked because of its sharpness and easily detectable even if the band width of the time series is not wide enough and if the delay time of the echo is small. Experiments of sound propagation and flexural wave propagation show the effectiveness of this method. Comparison between this method and correlation method is also shown., 資料番号: SA2401182000}, pages = {29--38}, title = {Detection of Echo by Linear Prediction}, volume = {40}, year = {1975} }
