yield value
Examples
- Using isppac10 to accomplish highly accurate adjustment of amplifier with arbitrary gain value
10实现放大器任意增益值的高精度调节 - A key in which the keyer signal is faithfully reproduced in the final key effect . linear keying preserves soft key edges , and generally has a gain of 1 , or unity
在最终的键效果中键控器信号被如实地复制的一种键。线性键控保持键的柔边，并且通常增益值取1或一致。 - Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber . whereas the spectrum of raman gain coefficient of optical fiber is not flat , the gain of signal light with different wavelength induced by a single pump is rather different , when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump , the gain spectrum of the wdm signal light is not flat . the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )
拉曼光纤放大器（ ramanfiberamplifier ,简称rfa ）利用高强度的泵浦光与信号光在光纤中的非线性相互作用实现信号光的直接放大，但是由于光纤的拉曼增益系数谱很不平坦，所以同一泵浦光源对不同波长信号光的增益就存在很大的差别,因此,用单泵浦光源来放大波分复用( wavelengthdivisionmulti - plexing ,简称wdm )信号光时，各信号光的增益值就有很大差异， wdm信号增益的平坦度对光信噪比( opticalsignal - noiseratio ,简称osnr )有重要影响。
