Convolution.

Description
Convolution formula is defined and explained. The convolution integral is the superposition of unit impulse responses. Numerical examples on this are solved. Connection of convolution formula with Laplace Transform is shown. Application of convolution formula in physics are discussed. General equivalent initial conditions for delta response are discussed. The convolution product is defined. This product is associative and commutative.
