I am using "spectrogram" function to a signal. Now I wish to convert back the original signal. Can anybody help me inthis regard? Is there any function to get back the original signal like "inversespectrogram"?
Ex: t = 0:0.001:2; x = chirp(t,100,1,200,'quadratic'); [SE,FE,TE]=spectrogram(x,128,120,128,1e3);
Here SE=spectrogram coefficients, TE=Time and FE=Frequency. Now I wish to get back my original signal "x". Please help me.
Thank you in advance.
