【Abstract】 The market possession of digital phase shift IC is increasing gradually due to its predominant performance. In practical terms, the bad circumstance, such as the unstable frequency of industrial power net, the aberrant waves, affect the normal operation of equipment seriously. The paper analyzes the results of input noise in detail and gives the resolving method. It affords the algorithm, circuits and experiment results. The method is of engineering practical value.更多还原
