摘要
Matlab作为一款具备强大科学计算能力和图形显示功能的软件在语音信号处理领域得到了广泛的应用。本文研究了在Matlab环境下的FFT频谱分析原理及其显示,并对采集信号的纹理图像进行了傅立叶变换,实现了傅立叶能量谱。实验证明Matlab对语音信号的频谱处理十分简单方便,易于实现。
As a scientific software with the chahacteristic of powerful computing capability and strong graphical display,Matlab has been widely used in speech signal processing field. This paper introduces the principle of FFT firstly under the environment of Matlab,and Fu Liye transform of the texture image signal.It realizes Fu Liye energy spectrum.Matlab can execute those analysis and processing simplely and conveniently.
