采用單片機的同步外差相敏檢波器

The Synchronous Heteredyne Phase Sensitive Detector Using Single Chip Microcontroller

  • 摘要: 分析了同步外差相敏檢波原理和性能,進而采用8098單片機控制下工作的數字移相器構成同步外差相敏檢波系統,并進行了測試.

     

    Abstract: In this paper, the performance and principle of the synchronous PSD have been analysed. Using the digital phase shifter controlled by the 8098 microcomputer, the synchronous heterodyne PSD system has been researched and test have been carried out.
