The input-output relationship of a linear system is given by $y(t) = \int_0^1 [x(\tau) + x(\tau - 1)]d\tau$. Then the transfer function $H(f)$ of the linear system is A) $\frac{1}{j2\pi f}[1 + e^{-j4\pi f}] + \delta(f)$ B) $(\frac{1}{j2\pi f}[1 + e^{-j4\pi f}] + \delta(f))^2$ C) $\frac{1}{j2\pi f}[1 + e^{-j2\pi f}] + \delta(f)$ D) $\frac{1}{j2\pi f}[1 + e^{-j4\pi f}] + 0.5\delta(f)$ E) $(\frac{1}{j2\pi f}[1 + e^{-j2\pi f}])^2$
