| Abstract: | This paper de rived the frequcncy characteristic of the trapezoid-window function, the amplitude-freqency characteristic expressions were achieved. Compared with the amplitude-frequency characteristic of the window functions often used at present, its property has an advantage over the rising-cosine function improved. |
