Q1:

A pulse function having magnitude E and duration from t = 0 to t = acan be represented as

A sum of two pulse functions

B difference of two pulse functions

C difference of two step functions each of magnitude E and one originating at t = 0 and the other at t = a

D none of the above

ANS:C - difference of two step functions each of magnitude E and one originating at t = 0 and the other at t = a

v(t) = Eu(t) - Eu(t - a).
