Abstract
Digital signal processing is a cross-cutting nature of the subject, has become the theory and practice, in the hi-tech field occupies an important position in one of the subjects, and increasingly improve and mature. And the signal system can be analyzed in the time domain, can also frequency domain. Spectral analysis is the frequency domain analysis, spectrum refers to the spectrum, which is in the frequency domain signal analysis, some laws. MATLAB digital signal processing technology is an important means of achieving. With the signal processing applications continued to expand, the general signal processing to meet the need. MATLAB and the signal processing toolkit also with the signal processing theory and method of development and development. At the same time, as well as signal processing theory and method of achieving and engineering application to provide a limited help.
This thesis is about the signal spectrum analysis in several ways, including classical and modern method of analysis used in several ways.
