Показать описание
In this lecture the process of calculating convolution of two discrete time signals is explained in details.
There are following three methods of calculating convolution:
Graphical method
Matrix Method
Tabular method
Graphical method and Matrix method are discussed in this lecture.
Graphical method is a conventional method which is long but easy while matrix method is very simple and easy method but it is convenient to apply only on signals in which number of nonzero values are small (generally below 6).
