I have this signal shifted by 7000 on the t axis
g(t) = 4000 * sinc(4000 * t) * e^(j * 2 * pi * 7000 * t)
I tried to replicate this in matlab to get the sinc graph, but does not work:
j = sqrt(-1);x = linspace(-9000,9000);y = (4000 * sinc(4000 * x)) * (exp(j * 2 * pi *7000 * x));plot(x,y)grid
Can anyone help me? Thanks!
