1）已知2N点实数序列 N=64。用一个64点的复数FFT程序，一次算出 ，并绘出频谱 。 （2）已知某序列 在单位圆上的N=64等分样点的Z变换 。用N点IFFT程序计算 ，绘出图像 。 (1) known 2N-point sequence of real numbers N = 64. With a 64-point complex FFT process, a calculated and mapped the spectrum. (2) known to a certain sequence in the unit circle on the N = 64 sub-samples of the Z transform. N-point IFFT procedures used, the mapped image.)
