What is inverse multidimensional Fourier transform?
The inverse multidimensional Fourier transform is given by The multidimensional Fourier transform for continuous-domain signals is defined as follows: Similar properties of the 1-D FT transform apply, but instead of the input parameter being just a single entry, it's a Multi-dimensional (MD) array or vector.
Why is the Fourier transform used in Bochner's theorem?
The Fourier transform may be used to give a characterization of measures. Bochner's theorem characterizes which functions may arise as the Fourier–Stieltjes transform of a positive measure on the circle. Furthermore, the Dirac delta function, although not a function, is a finite Borel measure.
What is the 2-D Fourier transform?
The 2-D Fourier transform is a basis for both analysis and implementation of multichannel processes. Consider the six zero-offset sections in Figure 1.2-1. The trace spacing is 25 m with 24 traces per section. All have monochromatic events with 12-Hz frequency, but with dips that vary from 0 to 15 ms/trace.
