摘要
介绍了傅立叶变换、小波变换等几种常见的分析处理信号的方法,并对一个实例信号分别利用这两种方法进行了分析处理,阐明了这两种变换在对信号处理上的不同特点。
Some familiar approachts for analyzing and transacting signals based on Fourier transform and wavelet transform are introduced in this paper. An example signal is analyzed and transacted by using the Fourier transform and wavelet transform, which clarifies the differences for transacting the signal by the two ways.
