Recursive PLL of the First Order

This paper describes a new type of Recursive Phase Locked Loop (PLL) of the first order. The PLL is a linear discrete system described by two recursive equations. The hardware implementation of PLL is described. Different analyses of PLL parameters are made. Computer simulation of PLL is introduced in order to give better insight into the PLL characteristics and to confirm the mathematical analyses, too. Made analysis shows that PLL is suitable for different applications. Precise digital phase shifting of pulse rate is one of the applications which is described. The picture of the input and output pulse rates, recorded on the simulated PLL by professional software package “Multisim”, is presented.
