fft(fast fourier transform meaning in Chinese
快速热欧姆转换
Examples
- Secondly , the sub - function blocks of fft ( fast fourier transform ) are finished in max + plus ii software platform , and each of them has been designed carefully and simulated in the software
然后用max + plus软件平台编程实现快速傅立叶变换的各个软件模块，并进行了大量的逻辑设计和软件仿真。 - The future trends of power quality are discussed . this thesis also brings forward the method of power quality measurement , i . e . the integration of wt ( wavelet transform ) , fft ( fast fourier transform ) and ann ( artificial neural network )
初步对电能质量监测问题和本文的发展方向进行了展望，提出将小波变换、离散傅立叶分析和人工神经网络相结合将是很有前途的方法。 - Though the two new methods can improve the effect of edge detection , they need the gabor and wavelet transforms which make the computation complex and cost much time and are not easy to used in real - time application . this paper presents an efficient fast approach to compute real discrete gabor coefficients by applying the fht ( fast hartley transform ) in gabor transform , also the fft ( fast fourier transform ) is proposed to used in compute the wavelet coefficients
虽然gabor和小波的引入能提高边缘检测的效果，但往往因其计算的复杂性而受到限制，本文提出了一种有效的离散gabor变换算法来计算有限离散实数信号的gabor系数，同时，也给出了基于fft的小波变换快速算法，为理论的快速实现提供了可能性。
