Heaviside Function. The Heaviside or unit step function (see Fig. 5.3.1) , denoted here by uc(t), is zero for t < c and is one for t ≥ c; that is, uc(t) = {0, t < c; 1, t ≥ c. The precise value of uc(t) at the single point t = c shouldn’t matter. The Heaviside function can be viewed as the step-up function.
