常見例句雙語例句The characteristics extraction and analysis of radar intra-pulse mixed-signal is an important task in ECM.雷達脈內混郃信號的特征提取和分析是電子對抗領域的重要研究課題之一。Secondly, the output waveform signal generator can be divided into sine wave signal generator, pulse-wave signal generator, function generator and arbitrary wave generator, and so on.其次,按輸出波形又可分爲正弦波、脈沖波、函數發(fā)生器和任意波發(fā)生器等。Chirp signal is a kind of pulse-compressed signal with large time-bandwidth products achieved through linear frequency modulation. It has high resolution in range because of its great bandwidth.線性調頻信號是通過線性頻率調制獲得大的時寬帶寬積的一種脈沖壓縮信號,具有大的帶寬,因此有高的距離分辨力。權威例句Pulse-code modulation is simply a way of representing the analog electrical signal, in digital form.ENGADGET: Primed: digital audio basics Mobile 返回 pulse signal
