The primary factor affecting fast phase lock is analyzed by using MATLAB. Then a fast all digital phaselockedloop with a high precision automatic modulus control is proposed.
The phase- lockedloop is one kind of control system which is able to achieve phaseautomatic lock, to compose frequency and to trace demodulation system.
