| Abstract: | This paper analyzes the spectrum structure of a sort of nonuniformly and nonideally sampled signals and obtaines the digital spectrum representation of it in closed form. The digital spectra of periodic signals are discussed and some important properties are explored. At last we give an application bout the spectrum analysis of digitally syntheesized periodic signals. |
