The continuous unit step function and the unit impulse are discussed

Introduction to some basic properties of a system . These properties are memory,time invariance ,causality and linearity .

Introducing to the convolution integral representation of LTI system.

The convolution sum representation of LTI system

1. The eigenfuctions and eigenvalues of LTI systemsThe importance of the responses of LTI systems to complex exponential signals lies in the fact that the responses are a constant times the correspo

Two basic signals in signals and system analysis are the unit impulse and step functions . For example , we can use the unit impulse to construct and represent other signals . Here, the unit impulse and step functions in discrete time are introduced.
