本文提出一種經接收由外部傳進的類比訊號後，經過轉換成為數位訊號，透過現場可程式化閘陣列（FPGA）進行訊號解調等處理，再經由通用串列匯流排（USB）傳進電腦，最後由電腦軟體負責顯示、儲存的一種平台。藉由FPGA的多樣化設計性與USB 2.0的高速傳輸，達成一種可以由電腦方便地顯示、分析、儲存訊號的傳輸平台，而且接收的類比訊號，讓電腦參與類比訊號的接收可以有更簡單直接的方式，達到以軟體無線電為基礎的接收平台。 In this thesis, we achieve a platform that receives analog signals and converts them into digital signals. By using Field Programmable Gate Array, this platform processes the digital signals in demodulation or others processes. The processed signals be passed to personal computer by Universal Serial Bus. Finally, the computer’ program shows or saves the signals. We realize this platform in the idea of FPGA’s variously design and USB’s high speed. And the signals received by computer are analog. The platform supplies a convenient and direct way for computer in processing analog signals. The purpose is to realize a receiver platform that is convenient by using computer to show, analyze and save the signals. This platform uses the idea of Software Defined Radio.
