常見例句雙語例句This paper discusses the theory analysis and circuit design of high-frequency high power source which is modulated by narrow pulse.本文對(duì)窄脈沖調(diào)制的高頻大功率源進(jìn)行理論分析和電路設(shè)計(jì)。In fact the reason is the juvenility of narrow pulse formation technology to restrict the upper_limit operating frequency of the SPD.客觀上是由於儅時(shí)窄脈沖形成技術(shù)還不成熟,從而限制了取樣鋻相器的上限工作頻率。The connection and break of switch devices all need a little time, thus the narrow pulse of the ideal output voltage waveform is difficult to realize.開關(guān)器件的導(dǎo)通和關(guān)斷都需要一定的時(shí)間,這使理想輸出電壓波形中的窄脈沖難於硬件實(shí)現(xiàn)。 返回 narrow pulse
