![]() ![]() ![]() x4 (t) is sinc(t) contracted by a factor of 10. It is obvious from the definition of sgn(t) that sgn(2t) = sgn(t). Note that the sum of the left and right side of triangular pulses that are displaced by one unit of time is equal to 1, The plot is given belowģ. ![]() N=0 Λ(t − n) is a sum of shifted triangular pulses. This indicates first we have to plot Π(2t) and then shift it to left by 5 2.
