| Abstract: | In this paper, We studied the parallel Computational algorithm of Fast Fourier Transform and its implementation in YH-1 Computer. The result of Computation indicated that developed parallel algorithm is very effective and the efficiency of yecter operation has been enhangced by dozen times as Compared with Conventional scalar operation of FFT. |
