- Abstract
Phase-locking amplifier technology belongs to one of significant branches in scientific research field of detection of weak photoelectric signals and also one of important and effective methods of detecting weak signals. Digital phase-locking amplifiers available now usually are realized based on DSP or PC system, its relevant operations on digits belong to software algorithm essentially and complicated in algorithm, which have higher requirements on microprocessor. Therefore, this thesis has put forward a new method of design of digital phase-locking amplifier based on circuit structure relevant to digits in new type, simulation on Matlab software in demodulation algorithm relevant to digits.
