例句與用法
- A functional unit that modulates and demodulates signals . one of the functions of a modem is to enable digital data to be transmitted over analog transmission facilities
一種對(duì)信號(hào)進(jìn)行調(diào)制與解調(diào)的功能部件,調(diào)制解調(diào)器的功能之一就是使數(shù)字?jǐn)?shù)據(jù)經(jīng)由模擬傳輸設(shè)施進(jìn)行傳送。 - J . mitola proposed software radio ( or software defined radio , sdr ) technology to deal with those problems , i . e . , digitizing waveforms as near as possible to rf , and modulating / demodulating signals by software
針對(duì)這些問題， j . mitola提出了的射頻信號(hào)數(shù)字化、軟件化處理的思想，即軟件無線電技術(shù)，成為解決上述問題的有效途徑。 - The method is given to solve the problem in adaptive demodulation that adjudgement will worsen when the snr is low . by using the error signals to reduce the demodulated signals , the bit error rate will be improved
仿真中,針對(duì)dpsk信號(hào)的自適應(yīng)解調(diào)中小信噪比下門限失效的問題,提出了利用誤差改進(jìn)門限判決的方法,將誤碼性能提高了1 2db 。 - The test results show that different patterns of pd correspond to different demodulating signal waveforms , the pd phase angle in ac , and spectrum characteristics . therefore the pd patterns can be recognized by the uhf characters of different pd signals in gis
試驗(yàn)結(jié)果表明，不同缺陷類型的局部放電在其檢波信號(hào)波形、局部放電工頻相位分布和超高頻頻譜特征是有所不同的，可以依據(jù)這些特征對(duì)gis內(nèi)的局部放電類型進(jìn)行識(shí)別。 - A gis pd measuring system is established , including a conventional pd measurement system , uhf detecting system and a pd spectrum system . we can obtain pd signal characters by this system , such as uhf transient signal waveforms , uhf demodulating signal waveforms , the pd phase angle in ac , pd spectrum , and discharge quantities
