spectrogram unit change from dB/Hz to linear scale

Hi,

I am using readymade matlab function to plot the spectrogram of my data. I want to change the spectral intensity unit from dB/Hz to linear scale.

Please let me know how can I do that.

Thanks :)

If you want dB rather than dB/Hz, use the pspectrum function with the 'spectrogram' option argument.

To get magnitude from dB, use the db2mag function.
