pulse envelope造句
例句與造句
- With the development of few - cycle pulses ( fcp ) , the phase shift of the optical carrier with respect to the pulse envelope becomes non - negligible
隨著周期量級激光脈沖的產(chǎn)生，脈沖載波及包絡(luò)之間的相對相位漂移逐漸成為不容忽視的問題。 - As compared with the solution using pulse envelope representation , the propagation equation using complex analytic signal representation reveals different spatiotemporal behaviors such as spectrum redshifting , narrowing , and pulse broadening , etc . 2
復(fù)解析信號解會出現(xiàn)光譜紅移、變窄、脈沖變寬等與脈沖包絡(luò)解不同的時空特性。 - The method can measure the following parameters , ( pulse attitude ) pa , ( pulse width ) pw , ( time of approach ) toa , snr , ( radio frequency ) rf , pulse envelope characteristic parameters and intra - pulse modulation parameters with a high precision and a high discrimination
該算法能夠分析雷達(dá)信號的脈沖脈幅、脈寬、到達(dá)時間、信噪比、載頻、脈沖包絡(luò)特征參數(shù)和脈內(nèi)調(diào)制特征參數(shù)。 - Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation , and the interpretation of this phenomenon is also presented . it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope
數(shù)值分析的結(jié)果表明，當(dāng)脈寬小于光波周期時，相位的作用開始顯現(xiàn)出來，當(dāng)脈寬比光波周期長時，載波相位的作用可以忽略，并分析了相位起作用的原因，用解析的方法說明正是相延遲和群延遲之間的差別造成了光載波在脈沖包絡(luò)下的滑動。 - Shapes of pulse envelope are found to have some effect on the degree of phase influences . dependence of single - cycle pulse ( scp ) energy on the carrier phase has been studied for gaussian , lorentzian , hyperbolic secant and sine shapes respectively , which shows that these energies can be expressed in the same form . phase effect on pulse with gaussian envelope is the first to show , then are hyperbolic secant and lorentzian pulses , and sine the last
包絡(luò)對載波相位的作用范圍也是有一定影響的，我們對高斯、洛侖茲、雙曲正割和sinc四種不同包絡(luò)的脈沖，研究了單周期脈沖能量隨載波相位的變化規(guī)律，發(fā)現(xiàn)以上四種脈沖的歸一化能量均可在形式上用同一表達(dá)式表示，并發(fā)現(xiàn)對于這四種不同包絡(luò)的脈沖，高斯脈沖相位的作用最早體現(xiàn)出來，然后是雙曲正割和洛侖茲脈沖， sinc脈沖最遲。 - It's difficult to find pulse envelope in a sentence. 用pulse envelope造句挺難的
