一、信号 + View Code 二、绘制时域信号 + View Code 三、FFT变换、并绘制-幅值、实部、虚部 + View Code 可以看出频域中的点关于(N/2)对称,所以只需要观察(0:1:N/2) 四、更改相位 幅值不受影响,但实部或虚部的值,会出现0的情况==>看MATLAB中FFT的频谱,应该看幅值 绘制半谱图(幅值的)后--我们发现-...

I try to figure out how the FFT command works on matlab and I came across this example that matlab central gives out at this linkhttp://www.mathworks.com/help/matlab/ref/fft.html Can somebody explain to me how this code works?? If not all the code than this part of it ...
on the data size and computation. Similarly, Simulinkprovides blocks for FFT that can be used in Model-Based Design and simulation. MATLAB and Simulink also support implementation of FFT on specific hardware such as FPGAs, processors including ARM, and NVIDIA GPUs, through automatic code ...
Matlab FFT的使用1
OUTPUT[i] = sqrt(x[i].real*x[i].real + x[i].img*x[i].img)*1024; matlab代码中: subplot(2,2,3); plot(abs(z));title('IFFT'); 所以IFFT的结果将sin函数的负y轴数据翻到了正y轴。另外,在CCS v5的图形中我们将显示信号的幅度放大了1024倍便于观察,而matlab中没有放大。
