快速傅里叶变换在频谱分析中的应用
Application of Fast Fourier Transform in Frequency and Spectrum Analysis
摘要
Abstract
Based on fast Fourier transform principle and Cooley-Tukey fast Fourier transform algorithm, a new method of frequency and spectrum analysis which applies in digital signal processing (DSP) is presented, and the operational efficiency and memory space of the method are analyzed. Example shows that the new method have less amount of complex multiplication and small memory space which is fit for DSP. So the method is very suitable for MP3/MP4 or mobile phone and other consumer electronic products which use high-performance DSP.关键词
