摘要
离散时间傅里叶变换的性质是"数字信号处理"课程教学中的重要内容。本文以线性、时移和频域微分特性及时域卷积定理为例,分析其在传感器阵列信号处理和语音信号处理中的应用,对傅里叶变换性质的教学有一定的指导作用。
The properties of discrete-time Fourier transform （DTFF） are an essential part of teaching Digital Signal Processing Course. Taking the properties of linear, time-shifting, differentiation in frequency and convolution theo- rem in the time domain as examples, this paper analyzes the applications in sensor array and speech signal process- ing. This paper can serve as a significant guide in the teaching of DTFT properties.
