lead vs lag filter 对于filter的设计，主要要分析其零极点对loop gain 的稳定性的影响。 很多时候，有些学者会称lead or lag filter or lead lag filter。 是什么意思呢？ in frequency response design, the phase-lead or lead filter adds positive phase to the system over the specified frequency range. ...
以下参数的理解对PLL电路的学习和设计很重要。 - loop bandwidth - vco gain - damping factor - natural frequency - Q-factor - closed-loop transfer function - open-loop transfer function or gain - loop forward gain - radian frequency at which maximum phase margin located - phase margin loop ...
