Web22 de mai. de 2024 · 3.4: Frequency Response. The frequency response of an element or system is a measure of its steady-state performance under conditions of sinusoidal excitation. In steady state, the output of a linear element excited with a sinusoid at a frequency ω (expressed in radians per second) is purely sinusoidal at frequency ω. Web30 de nov. de 2014 · Under these conditions, the necessary loop gain to extract the clock needs to be greater than 1.256·10 6 s −1. As a consequence of this high gain, the filter needs to be carefully designed, in order to combine synchronization conditions and stability. 3.
