Convolution integral question

  1. Jul 10, 2010 #1
    cant understand the red arrow transition
    i changes the intervals and i cuts half of the arguent inside the integral
    i cant see why

    regarding the interval change
    the H function is 1 in a certain interval
    so if they change the integrval then its no longer H inside
    because we have taken the '1' part of the H

    regarding the cutting in half the argument inside the integral
    i have no idea

    The reason the integration limits change is because you're convolving two pulses that are only defined from -1 to +1, so the convolution is just 0 for all intervals other than -1 to +1.
