Multiple choice

The frequency response of a linear, time-invariant system is given by H(f) = $\dfrac{5}{1 + j10\pi f}$ The step response of the system is

  1. 5 (1- e-5t) u (t)

  2. 5 $\left( 1 - e^{-\dfrac{t}{5}} \right) u(t)$
  3. $\dfrac{1}{5}$(1- e-5t) u (t)
  4. $\dfrac{1}{5}$$\left( 1 - e^{\dfrac{t}{5}} \right) u(t)$
