DfT is … WebIn mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a complex-valued function of frequency. The interval at which the DTFT is sampled is the reciprocal of the duration …

The database output value may be from category 1 (long half-life, >3 h) or category 0 (short half-life, <3 h). All the pharmacokinetic parameters (absorption, distribution, metabolism, and excretion) are summarized in Table 3.
