Earthquake Dream Symbol â An earthquake is a disturbing symbol in a dream, denoting life changes that may be catastrophic. It represents very physical things. Everything that causes your sense of stability is or may soon be in jeopardy, as indicated by the literal ground beneath your feet giving way in your dream.
The wavelet analysis is done in a similar way to the STFT analysis, in the sense that the signal is multiplied with a function, {\it the wavelet}, similar to the window function in the STFT, and the transform is computed separately for different segments of the time-domain signal.
From Wikipedia, the free encyclopedia. Fourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation.he Fourier transform spectrometer is just a Michelson interferometer but one of the two fully reflecting mirrors is movable, allowing a variable delay (in the travel-time of the light) to be included in one of the beams. The Michelson spectrograph is similar to the instrument used in the MichelsonâMorley experiment.
