摘要
自紅外線光譜儀產生的DC訊號，經OP－AMP放大再經A/D轉換器轉變成數位資料，儲存於Apple II微電腦記憶中。以自製的FORTH 3.0採樣，資料可儲存在9000至BC00虛磁碟，磁帶及磁片中。採樣速度為57資料點／秒。儲存的光譜資料，經D/A轉換成線性訊號，再經記錄器繪出光譜圖形。資料亦可由DATA SMOOTH程式處理以減少雜訊。

The IR signal from spectrophotometer are amplified by OP-AMP and digitized with A/D converter. After sampling with FORTH 3.0, the spectral data are stored in 9000-BC00 pseudo disk, magnetic tape and floppy disk. The optimized sampling rate is 57 point/second. The stored data are plotted through D/A converter and recorder. The noise is reduced by DATA SMOOTH.
