| Abstract: | By accomplishing eight classical and modern digital signal spectrum estimation algorithms, this paper analyzed the effects and differences caused by these spectrum estimation algorithms among different signals including periodic signal, acoustical signal and random signal. From the attributes and differences represented by these algorithms we get the advantages and disadvantages of different spectrum estimation algorithms used to analyze different character signals. |
