Abstract
The author (1990) has previously established that Lyapunov redesign is effective in designing an analog phase-locked loop for which the nonlinear model (in the signal phase space) is guaranteed to be stable. This paper extends that concept to what are commonly called classical digital phase-locked loops. These loops, which are very common in high speed digital communications systems, use digital phase detectors but analog filters and VCOs.
