i'm doing behavioral model (MATLAB) for digital PLL
the most significant difference between DPLL and analog PLL is the filter
where digital loop filter of DPLL is consists of a proportional path and integral path (2nd-order system)
my problem is, for propotional path and integral path
should i use a PI controller rather than the realization as the picture shown?
Where the PI controller is in the discrete domain, and the picture shown is in s-domain (continuous)
2 methods come different results.
