Abstract
Various benefits of digital filters as compared to their analogue counterparts, are described. The characteristics of a linear system including stability, causality, superpositionality, and uniqueness of output, must conform to strict mathematical rules. Stability is self-evident and causality means that the output must depend only on inputs. Superpositionality means that output is sum of the system's responses to each of the signals considered. Uniqueness of output means that the system will always produce a unique output to a unique input. All the linear systems follow a single equation of convolution integral, which encapsulates their response.
