引言在上一小节中,我们分析了Radix-2 DIT FFT的基本原理。本小节将介绍Radix-2 DIF FFT的基本原理。 基本原理设序列 x[n]的长度为N=2^M,M为整数。我们首先将x[n]分为两个长度为N/2的两个子序列。则x[n]的DFT可以…
问输出实现的“迭代FFT DIT Radix2”算法matlab的问题EN不用 for, if，直接 length(find(diff(a) == 1)) 就可以了 如果非要用for, if s = 0; for n = 1:length(a)-1, if a(n+1) – a(n) == 1, s = s + 1; end end s matlab 基本语句 1.循环语句for for i=s1:s3：s2 循环语句...
