    It would stretch in the horizontal direction - not the vertical direction. @Akshay Budhkar is correct in that sense.

    @imranmeah91 - there is nothing in the question to indicate that rect is a periodic function

    oh amplitude "if rect(t) is function between -1/2 to 1/2 " i think this lines suggests it's periodic nature

    |dw:1326849951351:dw| one possibility is it could asymptote towards the two limits

    the only information given is that its range is between -1/2 and 1/2

    unless you are saying that this is some well known function named "rect"

    yes , there is http://en.wikipedia.org/wiki/Rectangular_function

    that still does not look periodic to me. I think all we can say is that is would stretch it horizontally
