    Abstract: 本文旨在提出一個簡單的方法,以?交越點演算法為基礎,檢測電?訊號之頻?。首先?用傅??演算法作為?位?波取出訊號中的基頻正弦和餘弦部分,再以?交越點演算法技術應用到正弦或餘弦信號,以計算該弦波訊號之頻?。計畫中將此??發展應用於個人電腦中,以分析運算所擷取出的訊號, 而電腦配備需具有DAQ(Data Acquistion Card) 設備和圖控式軟體LabVIEW,將所取得的訊號?出並儲存在記憶體中,再用?交越點演算法確定信號頻?。此開發系統可模擬產生帶有高次諧波及雜訊的訊號源,並?用程式平台估算其基頻弦波訊號之頻?。實驗證明,?交越點演算法是一種?測頻?的有效方法。
