Open in MATLAB Online hello , Iwant to plot fft of chirp signal. I am using chirp signal block from simulink and connected to zero order hold and then FFT spectrum scope but when i am running simulation, thdisplay of spectrum scope not displaying anything. ...
1. I have 2 signals x and y. Though i get a similar shape of the plot, the power amplitude differs when I use fft or pwelch. Would there be any reason for this? 2. When plotting, why do we need to plot with 10*log10(pxx) instead of only using pxx? Even when I use either ...
Plotting of FRF curvesPlease format your code:http://www.mathworks.com/matlabcentral/about/answers/I had only asked this question in that link also.Thank u very much for ur answer.But I have tried many ways of setting x- axis but not getting correctly.I request u to kindly provide me ...

MATLAB Online에서 열기 Hi, I'm using the FFT to compute the FT of some data, and follow the example code used on the Mathworks FFT help page (shown below): Fs = 1000;% Sampling frequency T = 1/Fs;% Sample time L = 1000;% Length of signal ...
MATLAB Online에서 열기 You've got some errors in your code, for example, you defined x=fftshift(s) which is wrong. You also add a normally distributed random amount with standard deviation 2, which is larger than the maximum amplitude of sinc function. ...
