Hello, I am using the FFt to convert a time series signal into images by reshaping the matrix (N*N). But i am having hard time to get the original signal back from the images. IS it because in fft i am considering only the magnitude of the signal not the phase of the signal ? Is there any way to solve this proble. May be using STFT ot any kind of other techniquesHello, I am using the FFt to convert a time series signal into images by reshaping the matrix (N*N).
