Jelaskan the inverse transform dari Analisis Fourier dalam bahasa sunda

conventions for amplitude normalization and frequency scaling/units

tabulated transforms of specific functions

an extension/generalization for functions of multiple dimensions, such as images

For use on computers, a useful "discrete-time" function can be obtained by sampling a "continuous-time" function, s(t), which produces a sequence, s(nT), for integer values of n.  The DTFT is equivalent to the Fourier transform of a "continuous" function that is constructed by using the sequence    to modulate a Dirac comb.  In that case, the integral formula above simplifies to a summation:

which is a periodic function, with period   An alternative viewpoint is that the DTFT is a transform to a frequency domain that is bounded (or finite), with span

The DTFT can be applied to any discrete sequence.  But in the particular case where s[n] are samples of s(t),    and  are closely related.  See Discrete-time Fourier transform for more information on this and other topics, including:
