Yooo
Newbie level 1
Hi,
I'm new in DSP and I'm trying to build my own spectrogram Matlab function. I don't want to use the built in function in the Matlab since it doesn't give me the required output. I will use the spectrogram to plot my (non-stationary) signal in the time-frequency domain usnig the tfsa toolbox.
the reason i don't use the built-in function, coz when I used it on a sinsoidal signal with frequency at 50HZ it gives me the plot at 0.25 HZ !! so I need to callibrate it.
I would appretiate any help ,,
thanks
