demodulated function 中文意思是什麼
-
As another application instance, a subsystem monitoring ultra - high frequency partial discharge of transformer is developed, which can analyse, process, plot time - domain pd data and demodulated pd data, besides, it also has such discharge type recognition function as spectrum calculation and auto correlation
作為另一應用實例，研製了變壓器超高頻局放監測子系統，此系統具有分析、處理、顯示超高頻時域波形及其包絡線波形數據的功能，還具有用於放電模式識別的時域波形及其包絡線波形的頻譜計算和自相關處理等功能。 -
The correlation detection using the periodicity of the direct sequence autocorrelation function can estimate the symbol period at intermediate frequency or at baseband. simulation results indicate that the former is superior to the latter when the demodulated frequency is unequal to the carrier frequency
時域相關檢測方法利用擴頻信號的周期自相關特性，能在中頻和基帶對擴頻碼周期進行估計，模擬結果表明中頻檢測時性能較好。
