I am writing a code to plot a real time mic recorded audio. I am able to plot the fft. I also want to plot a small portion of that fft say milli secs of that fft. can someone help with this? thanks. 댓글 2

of a shifted time series and my graphs are not appearing as I expect them to:To plot the FFT of a shifted time series and understand its behavior, it is important to ensure that the time and frequency domains are correctly handled. The current code has a few issues that need to be ...
I am tring to export the fft analysis result from fft tools in power gui to excel. I have 4 input signal available and 3 signal number (i.e. it is a 3 phase sytem with 4 different currents). I tried to export it to MATLAB command window using following command....

above graph. The Matlab help states I can use the Spectrum Analyzer to do that but idk whats wrong with my copy of matlab that there is no such thing as Distortion Measurements in Tools > Measurements. Here is an image of what I want to plot...
how to create model in Simulink of MATLAB code? i was stuck in create FFT in Simulink and plotting frequency domain in Simulink.You can directly use a "MATLAB Function" block where you can encompass the FFT logic into a function and plot the data...

To see this in simulation is not trivial, for two reasons: first, the FFT itself also introduces a factor N, the length of the FFT, and second, as can be seen in the left plot of Fig. 1, the signal may obfuscate the noise because it is smeared out. The latter effect can be ...
