Convolution Convolution is the basic concept in signal processing that states an input signal can be combined with the system's function to find the output signal.

In electrical engineering, the convolution of one function (the input signal) with a second function (the impulse response) gives the output of a linear time invariant system (LTI).

The most common fast convolution algorithms use fast Fourier transform (FFT) algorithms via the circular convolution theorem.

If is the fundamental solution, the right side of the equation reduces to formula_10But since the delta function is an identity element for convolution, this is simply .

Form is function. Form is function.

The quotient of an even function and an odd function is an odd function.
