理想积分滤波器二阶环带宽的讨论
环路的3dB带宽与环路增益和滤波器的时间常数密切相关。增大滤波器的时间常数，减小环路增益可以使环路3dB带宽很小。

Book Description
Phase Locked Loops (PLLs) are electronic circuits used for frequency control. Anything using radio waves, from simple radios and cell phones to sophisticated military communications gear uses PLLs.The communications industry’s big move into wireless in the past two years has made this mature topic red hot again. The fifth edition of this classic circuit reference comes complete with extremely valuable PLL design software written by Dr. Best. The software alone is worth many times the price of the book. The new edition also includes new chapters on frequency synthesis, CAD for PLLs, mixed-signal PLLs, and a completely new collection of sample communications applications.
