external modulation

基本解釋

In this paper we presents using EDFA and linearized external modulation for microwave subcarrier multiplexed (MSCM) lightwave system.
本文提出了採用摻鉺光纖放大器（EDFA）和線性化外調制器在系統(tǒng)中進行優(yōu)化，以實現(xiàn)高副載波複用。
Based on single mode laser system, a new dynamical system under external periodic perturbation modulation is constructed and investigated by using of the numerical analysis method.
通過對單模激光混沌系統(tǒng)增加一個周期擾動，搆造一種具有外部周期擾動的新動力學系統(tǒng)，基於數(shù)值法研究了系統(tǒng)的混沌態(tài)在周期擾動下的動力學行爲。
From the view of external modulation by using the method of ratio of small earthquakes modulated by solid tide, we quantitatively analysed the small earthquake activities in Urumqi and Alma Ata.
