1-D Covolution

1-D Covolution

In mathematics and, in particular, functional analysis, convolution is a
mathematical operation on two functions f and g, producing a third function
that is typically viewed as a modified version of one of the original functions, giving the area overlap between the two functions as a function of the amount that one of the original functions is translated. Convolution is similar to cross-correlation. It has applications that include probability, statistics, computer vision, image and signal processing, electrical engineering, and differential equations.
