What is DFT in medical terms?
Editorials. Defibrillation threshold (DFT) testing is an integral part of implantable cardioverter-defibrillator (ICD) implantation. The primary functions of defibrillation assessment are to confirm appropriate sensing of ventricular fibrillation and to establish an adequate safety margin for defibrillation.

Why do we need Fourier transform?
The Fourier Transform is used if we want to access the geometric characteristics of a spatial domain image. Because the image in the Fourier domain is decomposed into its sinusoidal components, it is easy to examine or process certain frequencies of the image, thus influencing the geometric structure in the spatial domain.
Why there is a need of Fourier transform?
Fourier Transform is used in spectroscopy, to analyze peaks, and troughs. Also it can mimic diffraction patterns in images of periodic structures, to analyze structural parameters. Similar principles apply to other ‘transforms’ such as Laplace transforms, Hartley transforms.
What are the disadvantages of Fourier tranform?
The major disadvantage of the Fourier transformation is the inherent compromise that exists between frequency and time resolution. The length of Fourier transformation used can be critical in ensuring that subtle changes in frequency over time, which are very important in bat echolocation calls, are seen.
What are the different types of the Fourier transform?
aperiodic spectrum This is the most general form of continuous time Fourier transform.
