Gain peaking effect
Webphase margin will cause peaking in the closed-loop gain near the unity-gain frequency. Since the closed-loop gain amplifies the noise, this peaking increases the noise in that frequency range even more, thus increasing the total out-put noise. This effect can often be seen in spectral noise density plots like the one in Figure 2. WebBy combining a numerical solution for the EDFA and an analytical expression for FWM components generated through the cascade, the model allows a realistic system analysis which includes gain peaking effect, amplified spontaneous emission accumulation and the effect of dispersion management on the four-wave mixing efficiency.

The diuretic and blood pressure … WebResonant peaking occurs at around 2.5 MHz due to the inductance of the bead and the 10 nF ceramic capacitor. Instead of attenuating the fundamental ripple frequency at 2.4 MHz, a gain of 10 dB occurs. Other factors that have an effect on the resonant peaks are the series and load impedances of the ferrite bead filter.
