例句與用法
- In this method , the phase difference between two compared signals that have same nominal frequency can be converted into voltage signal by phase detector . the voltage signal varies linearly with the phase difference and can be displayed or recorded by some instruments
此方法是將兩個被比對的標稱值相同的標準頻率信號之間的相位關系，通過線性鑒相器轉換成與它成線性關系的電壓信號，并通過相應的設備進行顯示紀錄。 - The system can generate sweep frequency signal with frequency range from 100khz to 150mhz and power range from - 40dbm to + 18dbm , and measure the gain and phase of the crystal . according to the gain and phase information and the iec - 444 standard , crystal parameters can be calculated , such as nominal frequency , series resistance , shunt capacitance , motion capacitance , motion inductance , q factor and so on
該系統(tǒng)能產生頻率范圍達100khz 150mhz ，功率范圍為? 40dbm + 18dbm的掃頻信號，并能對晶振的增益和相位差進行測量，其測量結果按照iec - 444晶振測量標準進行實時處理和計算，從而得到晶振的串聯(lián)諧振頻率、并聯(lián)諧振頻率、等效電阻、靜態(tài)電容、動態(tài)電容、動態(tài)電感和品質因數(shù)等主要電參數(shù)。 - Because the nonlinearity of phase detector exists near 0 and 360 , the measurement precision is limited . according to the feature of each nominal frequency , two new measurement methods are discussed in the second chapter of this paper . the two methods can reduce the phase noise , eliminate the effect of nonlinearity and promote the measurem ent precision by taking measure
由于在0和360附近存在的非線性，限制了儀器的測量精度，所以在本文的第二章中通過兩種新的測量方法的討論，并根據(jù)各頻率標準相位噪聲的特點，針對性的采取措施和如何克服在0和360附近的非線性的影響，以達到提高測量精度的目的。
