增益比 meaning in English

ratio of gains

4 . pulse signal is researched when amplified by edfa . for signal with a frequency of 10 khz , the gain is about 3db higher than sequence signal amplification , but in time domain , aberrance occurred with the amplified signal
4 .建立了edfa非稳态放大模型,对频率为10khz的脉冲信号进行了实验分析,结果表明,其小信号增益比连续光放大提高了3db ,但输出脉冲存在畸变。
