Proofs of Parseval's Theorem & the Convolution Theorem ... The key step in the proof of this is the use of the integral representation of the δ-function.

In mathematics, the convolution theorem states that under suitable conditions the Fourier transform of a convolution of two functions (or signals) is the pointwise product of their Fourier transforms. More generally, convolution in one domain (e.g., time domain) equals point-wise multiplication in the other domain (e.g., frequency domain). Other versions of the convolution theorem are applicable to various Fourier-related transforms.

The two-dimensional extension of the convolution, Theorem 3.7, proves that if g [ n] = Lf [ n] = f ★ h [ n] then its Fourier transform is ĝ (ω) = f (ω) h (ω), and h (ω) is the transfer function of the filter. When a filter is separable h [ n1, n2] = h1 [ n1] h2 [ n2 ], its transfer function is also separable:

Proof: The convolution theorem provides a major cornerstone of linear systems theory. It implies, for example, that any stable causal LTI filter (recursive or nonrecursive) can be implemented by convolving the input signal with the impulse response of the filter, as shown in the next section.
