Undergraduate Notes on Convolution and Integration by Parts

The evaluation of convolution can be cumbersome and unpleasant for most students.In this paper, a novel and much simpler technique is presented.The intent is to convolve two signals given their start and end times.The technique was beneficial as it could easily be explained when it was introduced to undergraduate students in Signals and Systems class.Additionally, a simplistic method on integration by parts by only applying an arrow diagram method (ADM) is explained.The present paper better depicts the methodology with different illustrations.
