WebIt's based on hardware techniques of clock recovery that approximate a derivative. The PFB algorithm actually calculates the derivative to the numerical approximation required by setting the number of filterbank arms.

Furthermore, if PLL is used would it not change the phase difference between the signals when trying to synchronize them? Thank you for your time! bruce coyer
