• 中文摘要： 在本文中，我們比較了高階圓諧濾波器（High order circular harmonic fflter)與純相位圓諧濾波器(Pure phase circular harmonic filter)之間的優劣，雖然兩者在數位系統上同時擁有高識別能力，但純相位圓諧濾波器在光學系統中所展示 的輸出訊號較強。
• 英文摘要： A comparison of the performance of high order circular harmonic filtering and pure phase circular harmonic filtering is given. Both of these two filterings have high discriminating ability and, thus, they are comparable when implemented in a digital system. However, pure phase circular harmonic filtering is more appropriate for incorporation in an optical system because it gives a much higher output signal in this case.
