  • Abstract
    The frequency of a digital phaselock loop (DPLL) is necessarily quantized. Feedback around the quantizing nonlinearity leads to a steady-state limit cycle. Properties of the limit cycle were obtained by computer simulation, and are reported here. Empirical formulas for guidance in DPLL design were developed
