Spectrogram

Question

0 个投票

I have a simple sine signal (data) with a frequency of 6Hz, lasting 30 seconds. When I perform a spectrogram of data, I should get a time-frequency plot where 6Hz is the solid line, instead I get 0.1Hz, what am I doing wrong?

Do you have a webinar that shows how to perform spectrograms, STFT, etc?

Hi Liangiun, Mike has accepted this answer so it appears the issue is solved for him. If you are having trouble with spectrogram.m, please start a new post and make sure to include whatever code you have.
