I am doing some simulation on sub-synchronous resonance phenomenon...i need to do fft analysis and show that subsynchronous frequency components (tortional mode of oscillations) are present in the speed and torque signals of the synchronous machine.How can I...

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 ...
For example, something likeテーマコピーjitter = 1e-6*randn(size(t));% use normal random number as in the Simulink modeljitter(abs(jitter)>3e-6) = 3e-6*sign(abs(jitter)>3e-6);% cliptjitter = t + jitter;Or does each element of the jittere...
Open in MATLAB Online I have applied FFT on a mixed signal to find its component. Then I used low pass filtering to separate specifc signal component. However, when I applied inverse IFFT, I did not get the original signal back (the signal before the FFT). I th...
Open in MATLAB Online hello if your data lenght is very long, there is no reason why you could not getter better resolution with a standard fft remember that freq resolution df = Fs/NFFT so if like in this demo I choose NFFT = Fs = 40e3, my resolution is 1 Hz, still you...
Dewesoft fft(g) (attached) vs matlab fft(g) (attached) Question #2 According to a Mechanical vibration book, I have the next equation to find the FRF. I applied this but my FRF y axis value is too high so, I don't know If I didn't applied correctly. That information ...
在MATLAB Online 中打开 I am a beginner in Matlab and I wanted to get the power spectrum values from the audio sample of a given frame in a video. I tried doing this. [I,AUDIO] = step(videoFReader) y = fft(AUDIO) but it is giving me an error undefined function 'fft' for input...
I have got a question regarding noise removal. I am doing a sensor project, and I need to measure output signal from the sensors. Theoretically speaking, output signal should be sine wave.However, sensor itself has got sine-wave-like noise. Therefore the supercomposition of two waves forms ...
