Q2. State the condition for existence of Fourier integral.
Ans.: The sufficient condition for the existence of Fourier transform of a function f(t) is that the area under the function f(t) be finite. Hence, for the existence of Fourier transform is
The above absolute integrability criteria must be satisfied to give the guarantee for the existence of Fourier transforms.
