平均噪声系数 meaning in Chinese

average noise factor
average noise figure

The average gain and nf are 22 . 22db and 8 . 69db respectively . gain flatness under single and double lasers control are 0 . 69db and 1 . 51db . a gain - clamped dual - stage l - band edfa by utilizing backward c - band ase as control light is presented for the first time
2 .我们还提出了一种优化反射式edfa噪声性能的方案,通过利用高双折射环镜代替普通光纤环镜来抑制铒纤的前向ase ,双通放大器在1580 . 84nm ~ 1588 . 48nm范围内的平均噪声系数减少了3 . 7db 。
