With the fast developing of software radio and digital technique , it is hoping to build a digital signal receiver based on software radio technique in communication as well as radar system 隨著軟件無線電技術(shù)和數(shù)字技術(shù)的迅猛發(fā)展,無論是通信系統(tǒng)還是雷達系統(tǒng),都希望能夠構(gòu)建基于軟件無線電技術(shù)的數(shù)字接收機系統(tǒng),以提高系統(tǒng)的靈活性。
In this paper , the emphasis is laid on the principle of active electronic current transformer , especially on the sensor head , signal receiver , fiber optic communication , and computer interface 本論文著重對有源電子式電流互感器的原理進行了研究,特別是系統(tǒng)地研究了傳感頭、信號接收機、光纖傳遞部分以及計算機接口等各部分的電路結(jié)構(gòu)。
Through the internet , by using another transducer as signal receiver , the b & k hardware and ni software are networked connected , and are combined to give a complete signal process system 藉由單一水下聲音傳感器,控制發(fā)射八種不同頻率之水聲,用以仿真多枚傳感器功能;再藉由另一只傳感器之接收,經(jīng)由訊號處理及辨識達到簡易之內(nèi)定通訊及控制指令。
