How to Model a Phase-Locked Loop (PLL) in Excel – part#2

03/11/2011

This is a continuation of the PLL series of tutorials and it starts by implementing and testing the low pass filter created in the previous section. After that, the block diagram is updated and the presentation begins to show how to build the PLL model in a worksheet using the existing LPF formulas. [sociallocker][/sociallocker]
