  • Synchronizing signal recovery circuit for radiotelephones
    Patent number: 4592076
    Abstract: An improved circuit for synchronizing signal recovery particularly suitable for mobile radiotelephone operation is disclosed. The initializing circuit of the phase-locked loop in the data receiver is inhibited for a predetermined duration upon triggering of a "window mode" by either of a rising or falling pulse-edge in a sequence of "ones" or "zeros" in the received data. The window mode masks the invalid transitions in such sequences and prevents retriggering by such transitions.
