Applications of Discrete-Time Fourier Transform Properties
Huang Qing-hu · Journal of Electrical & Electronic Education · 2015
The properties of discrete-time Fourier transform( DTFT) are an essential part of teaching Digital Signal Processing Course. Taking the properties of linear,time-shifting,differentiation in frequency and convolution theorem in the time domain as examples,this paper analyzes the applications in sensor array and speech signal processing. This paper can serve as a significant guide in the teaching of DTFT properties.
