In signal processing, multidimensional discrete convolution refers to the mathematical operation between two functions f and g on an n -dimensional lattice that produces a third function, also of n -dimensions. Multidimensional discrete convolution is the discrete analog of the multidimensional convolution of functions on Euclidean space.

In this animation, the discrete time convolution of two signals is discussed. Convolution is the operation to obtain response of a linear system to input x [n]. Considering the input x [n] as the sum of shifted and scaled impulses, the output will be the superposition of the scaled responses of the system to each of the shifted impulses.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 ). The proof of the frequency shift property is very similar to that of the time shift (Section 9.4); however, here we would use the inverse Fourier transform in place of the Fourier transform. Since we went through the steps in the previous, time-shift proof, below we will just show the initial and final step to this proof: z(t) = 1 2π ∫∞ ...
