When amplifiers are cascaded, the later circuits receive noise at their inputs along with the signals. This noise can cause distortion. Also, if the amplification factor is too high, the slightest feedback can trigger oscillation, rendering an amplifier system inoperative. Amplifier Gain & Decibels...

This communication deals with optical noise measurements of an erbium-doped fiber amplifier with input signal. We are able to determine the net gain and the noise factor from only these low frequency electrical noise measurements and new simple relations. It is presented as alternative to optical ...
1) ratio of gain to noise temperature 增益与噪声温度比值 1. The principle and method are proposed to compute and measure the ratio of gain to noise temperature of this active array antenna system. 有源阵列天线系统的噪声是有源相控阵雷达系统噪声的主要成分,通过建立基于有源阵列天线系统的噪声分析...
As for the noise model, we use the Y-Factor method. Regards, -Oscar Up0TrueDown Ben Siegel7 年多前in reply toOscar Guevara Prodigy20points Thank you for the help. So if I understand Figure 45 correctly, with the 3 dB attenuator off, the gain range is ...
The gain factors G(m, k) are calculated based on the current signal spectrum and the noise estimation, then smoothed before being applied to the signal spectral values S(m, k). First, a noisy factor is computed based on a ratio of the number of noise bins to the total number of bins...

Continuing to increase frequency until f > fh, we find that the second square-root factor begins to dominate while the first remains at unity (we are now in the range of frequencies for which (5.26) was derived). This function is plotted as Fig. 5.8c and shows the band-pass ...
