multiplex signal中文什么意思
例句與用法
- In the first place , start with theoretic model of distributed fbg strain - sensing network , sensing principle of fiber bragg grating is analyzed and sensing model created . on the basis of analyzing advantages and disadvantages of several familiar multiplexing and demodulation techniques , a mixture multiplexing method that combines optical frequency domain reflectometry ( ofdr ) and wavelength division multiplexing ( wdm ) is proposed to address fbg sensing array . at the same time , tunable narrow - band light source , which is composed of wide - band light source and tunable optical filter , is adopted to demodulate multiplex signals
首先，論文從分布式光纖光柵應(yīng)變傳感網(wǎng)絡(luò)的理論模型入手，分析了光纖布拉格光柵的傳感機(jī)理，建立光纖光柵應(yīng)變傳感模型；在分析比較了常見幾種復(fù)用技術(shù)和信號解調(diào)技術(shù)的優(yōu)缺點(diǎn)基礎(chǔ)上，提出應(yīng)用光頻域反射復(fù)用技術(shù)和波分復(fù)用技術(shù)相結(jié)合的混合復(fù)用方法來解決光纖光柵應(yīng)變傳感網(wǎng)絡(luò)的尋址問題，采用由寬帶光源和可調(diào)諧光濾波器組成的可調(diào)諧窄帶光源來解調(diào)復(fù)用信號，通過理論分析和實(shí)驗(yàn)研究證實(shí)了系統(tǒng)方案的可行性。 - The thesis includes the design of hard circuit , pcb ( printed circuit board ) , driver and application soft involving a / d board and d / a board . the detailed functional modules consist of multiplex signals select module 、 analog digital conversion module 、 digital analog conversion module 、 pci protocol conversion module 、 driver and magnifying module 、 control logic 、 clock circuit and configuration circuit . the importance of the thesis is a / d board
