The tools can be used by a teacher as a teaching aid to explain basic concepts in Signal and Systems course. They can also be used by students as a learning aid. They are easy for use and can be used in different locations using different operating systems. %K web-based %K tools %K interactive %K signals %K systems %U http://online-journals.org/index.php/i-joe/article/view/896
