Is this a right process flow of stft and spectrogram

26 views (last 30 days)
Hi experts,
I am very new in digital signal processing, and thus in fourier transform. I spent last couple of days grasping the concept of FT, FFT, DFT, and STFT. I have created a flow chart showing the steps of getting spectrogram using STFT. Could you please take a look at the attached image and tell me if I misunderstood anything, or used any term incorrectly. I know this question is not directly related to Matlab, however, any suggestion will be highly appriciated. Thank you!!

For Short-time Fourier transform, MATLAB has an in-built function stft. This function is defined under signal processing toolbox. You may install this toolbox and use stft function to find Short-time Fourier transform.

Your interpretation is absolutely correct. Nice visualization!
