In addition , the emphasis of the thesis is the use of fast fourier transform ( fft ) in reactive power compensation 研究的另一個(gè)重點(diǎn)是快速傅立葉變換在無功補(bǔ)償中的應(yīng)用。
In addition , based on fast fourier transform ( fft ) , an effective and reliable carrier frequency detection method has also been designed in this thesis 此外,論文還設(shè)計(jì)了一種有效可靠的基于fft的載波頻率測量方法。
The concepts of filtering and sampling power system voltage and current signals for harmonic analysis using the fast fourier transform ( fft ) algorithm by a digital signal processor are introduced 軟件算法方面,系統(tǒng)采用傳統(tǒng)的快速付立葉變換( fft ) ,對(duì)采集的電壓和電流信號(hào)進(jìn)行頻譜分析。
But the computing amount of dft is so large that its practical use is restricted , especially real - time processing . in fact , we use fast fourier transform ( fft ) in practical engineering 但龐大的運(yùn)算量使得dft的實(shí)際應(yīng)用,特別是實(shí)時(shí)處理難以實(shí)現(xiàn),所以實(shí)際工程中用到的都是快速傅里葉變換( fft ) 。
Related techniques and their applications are briefly reviewed in this paper , the conventional cross - correlation algorithm and the cross - correlation algorithm based on fast fourier transform ( fft ) are discussed 本文簡要地回顧了piv技術(shù)的一些典型算法和應(yīng)用,研究了基本互相關(guān)算法和基于快速傅立葉變換的互相關(guān)算法。
