例句與用法
  • At the receiving end , a inverse process is performed . the system receives low rate data and the fpga reorganizes a frame of data which is decoded by the compression chip every 20 ms . the obtained pcm signal is performed d / a to restore the analog speech signal
    在收端進行相反的過程,接收低碼率數據,并由fpga重新組幀,送至主芯片解碼得到pcm信號,再作d / a變換,恢復出模擬語音,系統是全雙工的。
  • The system adopts an advanced specific speech compression chip based on ambe algorithm . it can achieve high compression rate at 4 kb / s . the system first performs a / d conversion on analog speech input to obtain pcm signal and the pcm signal was encoded by the main compression chip
    它采用了比較先進的基于ambe算法的專用語音壓縮編/解碼芯片,壓縮率高,可以將數字語音信號碼率壓縮至4kb / s ,且編碼速率可通過修改控制程序選擇。
  • In this paper , the method of in - bore abnormal phenomenon remote detecting is presented . considering of the multi - channel transient signals automatic acquisition , a project of pcm signal hardwire transmission data automatic acquire system is put forward . in this system , a pcm demodulate board is designed , it can decode the pcm code string which contain the information of the multi - channel transient signals , it also can catch the useful data automatically , and transmit these data to upper pc by rs485
    在該系統中,為了能夠解調出包含多路動態信號數據的高碼速率pcm信號,設計并制作了一種適用的pcm解調板,能夠從pcm碼流中恢復出位時鐘信號,從而與發送端保持位同步和幀同步,從而對pcm碼流可靠地解調、緩存,并能根據計算機設定的觸發條件自動地捕獲多路信號的有效段,然后利用rs485總線將這些數據可靠地遠傳至計算機以供顯示、分析和保存。
