Two recent methods of spectral analysis proposed by Siddiqui and Wang and by Damsleth and Spjotvoll are investigated in this study by using six Autoregressive Moving Average (ARMA) models generated data. It is found that Siddiqui and Wangs method is superior and is recommended for use. The results also show that both methods can fit Autoregresive models better than ARMA models.

本研究旨在測試兩種頻譜分析方法的優越性。此兩種方法分別係由Siddiqui & Wang及Damsleth & Spjotvoll所提出。用於測試的資料是由六種自廻歸移動平均（ARMA）模式所繁衍的樣本為基準。測試的結果顯示由Siddiqi & Wang所發展的方法較為優異，可供為日後頻譜分析的有利工具，另外此兩種方法對自廻歸模式的模擬效果較自廻歸移動平均的效果為佳。
