Question 1 1 pts Suppose x (t) is such that there is a jump from a height of 7 to a height of -9 at t = 4; that is, x (t) equals 7 just to the left of t = 4 and x (t) equals -9 just to the right of t = 4. It follows that the associated derivative signal $y (t) = \frac{dx(t)}{dt}$ must have an impulse of the form $a\delta (t - 4)$. What is the value of a?
