1.1.3 IFT

Оглавление

This transformation is the inverse operation of the FT. IFT, therefore, synthesizes a frequency‐domain signal from its spectrum of frequency components to its time domain form. The IFT of a continuous signal G(f) where −∞ < f < ∞ is described as

(1.2)

where the IFT operation from frequency domain to time domain is represented by .
