Digital to analog converter (DAC) can convert a discrete binary signal into an analog signal directly proportional to the value of the binary signal. 數(shù)模轉(zhuǎn)換器（DAC）將離散的二進(jìn)制數(shù)字信號(hào)轉(zhuǎn)換成與該數(shù)字信號(hào)成正比的模擬信號(hào)。
Using a binary-mapped constant weight modulation code (BCWMC) for the recording channel of a digital holographic data storage system can facilitate the decision on the detected signal. 在數(shù)字全息數(shù)據(jù)存儲(chǔ)系統(tǒng)的記錄通道中，使用二進(jìn)制映射等重調(diào)制碼有利於信號(hào)的檢測(cè)。
This article proceeded with tri - nary baseband signal combining with binary ones, and then analyzed multi -nary digital baseband signal's frequency spectrum based on alternating wave and steady wave. 從三進(jìn)制數(shù)字基帶信號(hào)入手，結(jié)郃二進(jìn)制，利用交變波、穩(wěn)態(tài)波分析了任意多進(jìn)制數(shù)字基帶信號(hào)的頻譜特性。
