Theory:
Convolution is a formal mathematical operation, just as multiplication, addition, and
integration. Addition takes two numbers and produces a third number, while convolution takes two
signals and produces a third signal. Convolution is used in the mathematics of many fields, such as
probability and statistics. In linear systems, convolution is used to describe the relationship between
three signals of interest: the input signal, the impulse response, and the output signal.
Convolution is an integral concatenation of two signals. It has many applications in
numerous areas of signal processing. The most popular application is the determination of the output
signal of a linear time-invariant system by convolving the input signal with the impulse response of the
system.
