tailieunhanh - Lecture Digital signal processing: Chapter 7 - Nguyen Thanh Tuan

After studying this chapter students will be able to understand frequency analysis of signals and systems. This chapter includes content: Discrete time fourier transform DTFT, discrete fourier transform DFT, fast fourier transform FFT. | 7 Frequency Analysis of Signals and Systems Nguyen Thanh Tuan . B 1 Department of Telecommunications 113B3 1 Ho Chi Minh City University of Technology Email nttbk97@ 1 Frequency analysis of signal involves the resolution of the signal into its frequency sinusoidal components. The process of obtaining the spectrum of a given signal using the basic mathematical tools is known as frequency or spectral analysis. The term spectrum is used when referring the frequency content of a signal. The process of determining the spectrum of a signal in practice base on actual measurements of signal is called . The instruments of software programs used to obtain spectral estimate of such signals are kwon as spectrum analyzers. Digital Signal Processing 2 Frequency analysis of signals and systems The frequency analysis of signals and systems have three major uses in DSP 1 The numerical computation of frequency spectrum of a signal. 2 The efficient implementation of convolution by the fast Fourier transform FFT 3 The coding of waves such as speech or pictures for efficient transmission and storage. Digital Signal Processing 3 Frequency analysis of signals and .
