What is the following graph if u(t) denotes step function?(a) u(t+0)(b

1.	What is the following graph if u(t) denotes step function?(a) u(t+0)(b) u(t)-u(t-1000)(c) u(t-0)(d) u(t)This question was posed to me in homework.Query is from Operations on Signals in portion Digital Signal Processing of MATLAB
Answer» Correct answer is (b) u(t)-u(t-1000) To explain I would SAY: The unit step SIGNAL extends from 0 to infinity. When we plot it in MATLAB, we bound it to a CERTAIN point in time. In this CASE, we have bounded it to 1000 units in time. HENCE, option u(t)-u(t-1000) is correct. Option a, c and d mean the same thing but it’s not possible to represent the unit step function graphically.
