Sampling and Convolution

We'll begin with a review of the convolution with an impulse function in the time-domain. The impulse function will be described in the frequency domain

Analytical Description of the Sampling. Sampling is discussed using the concept of convolution in the frequency domain.…

Laplace Transform

To view all the videos on the Laplace Transform, type in the search box the words "Laplace Transform".

Introduction.

Derived from the work of a British engineer Oliver Heaviside, the Laplace Transform remains a powerful tool and foundation in analyzing linear systems, especially involving feedback systems.

Finding the system response using the classical differential equations is difficult. On the other hand, the Laplace Transform technique makes it a snap… Continue

Discrete-Time Convolution

This video describes the discrete-time convolution and how it can evolve to a continuous time convolution. Superposition and time-invariance are discussed.
