Question

The Fourier integral theorem is given by​

Answer 1

Step-by-step explanation:

Moreover Cauchy in 1816 (and, independently, Poisson in 1815) gave a derivation of the Fourier integral theorem by means of an argument involving what we would now recognise as a sampling operation of the type associated with a delta function.

Answer 2

Answer:

Fourier integral theorem is given by Poisson in 1815J.

Step-by-step explanation:

• Fourier integral is a formula for the decomposition for the non periodic function to harmponic variables over a continous set of the values.
• The fourier integral was  given by the J. Fourier in 1811
• Then,poisson gave the theorem in 1815 independently and Cauchy gave a derivation of the theorem using an argument of sampling operation of the type associated with a delta function.
