中文拼音 [màikuānshīzhēn]
脈寬失真 英文
pulse-width distortion
  • 脈 : 脈名詞1. （動脈和靜脈的統稱） arteries and veins2. （脈搏的簡稱） pulse 3. （像血管的組織; 連貫成系統的東西） vein

  1. The circular monopole ultra - wideband antenna has not only the extremely wide band in frequency domain, but also stable phase center, which makes the antenna radiate and receive the short pulse signals without any distortion, and suitable for various ultra - wideband communication systems or the single antenna of other multi - frequency operating communication systems

    這種天線不僅具有極寬的阻抗帶寬，還擁有穩定的相位中心。這使得圓盤單極超寬帶天線可以不失真地收發時域短脈沖信號。所以該天線不僅適用於超寬帶通信中，還能夠作為復雜多頻工作系統的單一收發天線。
  2. The selection rule of the hysteresis width has been developed in order to make the thd and rms value of the output voltage to be the best with high efficiency, according to the principle of pulse density modulation

    根據脈沖密度調制技術的原理導出了使輸出電壓失真度最小、有效值最大，系統效率也較高的環寬取值公式。
  3. Signal distortion and countermeasure in a pwm type audio power amplifier

    脈寬調制音頻功率放大器信號失真分析與對策
  4. As a result, the ultra - wideband antenna must be able to radiate and receive the short pulse signals without distortion, in other words, the ultra - wideband antenna has to own several octave impedance bandwidth or more, and stable phase center, which enables the ultra - wideband antenna to transmit and receive short pulse signals without distortion

    這就要求超寬帶天線具有輻射和接收時域短脈沖信號的能力，即擁有幾個甚至十幾個倍頻程的阻抗帶寬，同時天線應具有穩定的相位中心以保證不失真地收發短脈沖信號。
  5. The system had auto startup and stop function by software. the dsp based motor control system had lower current harmonic, more efficient use of supply voltage than spwm, less switch loss. on the other hand, this system make a lower noise for the pwm modulation. frequency is up to 20khz

    本系統實現了電機的軟啟動、軟關斷功能，電機電流的諧波失真較少，電壓利用率比常規的正弦波脈沖寬度調制（ spwm ）有了較大的提高，器件的開關損耗也得到了明顯的減少。
  6. When the pulse width of input gaussian wave packet was reduced and the length of forbidden region retained, the result displayed the output signal distorted seriously and its spectrum changed very hard. a frequency above the cut - off frequency became the main frequency and the group velocity was below than c

    在保持截止區長度不變，而減小輸入高斯波包的脈沖寬度時，模擬顯示輸出波形嚴重失真，而且，頻譜也發生很大的變化，主頻已變為一高於截止頻率的頻率，群速度小於光速c 。
  7. The followings were discovered in the simulations of undersized waveguide : when the pulse width of input signal, a gaussian packet, is rather wide, the output signal distorted little. a superluminal group velocity 3. 21c was revealed when the wave packet crossing 50mm forbidden region

    對凹陷波導（ undersizedwaveguide ）的模擬發現：輸入脈沖寬度較大的高斯波包，模擬結果顯示輸出波形失真較小，經過計算得到電磁波包穿過長50mm的截止區時，電場的幅度衰減了- 41 . 5db ，群速度為3 . 21c 。
  8. In this paper, a new advanced general wide - band signal generator module is developed, which uses high speed fpga as its control - unit. the module can work in any system with different bandwidth and can generate any kind of lfm signal, whose bandwidth is less than 200mhz, and time - width is less than 870us

    該模塊具有標準的輸入輸出介面，不同波段、不同帶寬的雷達系統均能直接使用，可以產生帶寬200mhz以內、脈沖寬度870us以內的線性調頻信號，具有預失真功能，能補償系統的特性特性失真，還可直接通過4倍頻或8倍頻實現帶寬的擴展。
