An astatic phase-locked system for digital signal processors: circuit design and stability

Block-circuits of phase-locked systems, which act as frequency synthesizers and misphasing correctors, for timing oscillators of digital signal processers are designed. The characteristic of the phase detector is determined with a timing pulse multiplier and a low-frequency filter. Astatic correctors are introduced. The global stability of the synthesized system is investigated by the Lyapunov direct method.
