波形失真率 的英文怎麼說
中文拼音 [bōxíngshīzhēnlǜ]
波形失真率
英文
waveform deviation factor-
Signal distortion includes three kinds of distortion : frequency, phase and waveform
信號的失真分為頻率失真、相位失真和波形失真等三種。Under the control of microcomputer, the sine vave output is produced. base on the result, the spwm wave is static and reliable
從逆變環節的實驗結果來看，產生的spwm波穩定、可靠，輸出電壓波形失真度小，電壓波動率僅在2左右。It also studies the influencing factors including sampling frequency, pd waveform, decline time, time intervals between pd pulses, mother wavelet, center frequency of interference, entropy threshold value and snr. in addition, it applies wavelet packet method （ wpm ） for non - stationary signal de - noising in on - line pd monitoring and analyzes the processing results under different pd waveform, sampling frequency and noise level. firstly, the curve of pd
基於小波包變換的非平穩信號消噪演算法（ wpm ）已較為成熟，本文將其應用於局部放電在線監測，通過研究其對不同局放波形、采樣率、噪聲水平下的處理效果，首次提出了理想白噪聲條件下提取局部放電信號的曲線，分析了各種因素對該演算法下信號失真的影響。Influence of frequency and wave distortion on the verification of phasemeter
頻率和波形失真度變化在相位表檢定中的影響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 。When the input voltage varies from 40v to 60v and the output side varies from no load to rated resistance load, the output voltage will vary within 1. 3 % with the thd of less than 2 % and the highest efficiency of 86. 3 %
當輸入電壓變化、輸出從空載變化到額定阻性時，輸出電壓變化量小於1 . 3 ，正弦輸出電壓波形失真度小於2 ，變換效率最高為86 . 3 ，額定阻性負載時效率為84 . 4 。分享友人
