Each diode cut-in voltage is \(0.7 \mathrm{~V}\) for the circuits shown in Figure P2.33.

(a) Plot \(v_{O}\) versus \(v_{I}\) over the range \(-5 \leq v_{I} \leq+5 \mathrm{~V}\) for the circuit in Figure P2.33 (a) for (i) \(V_{B}=1.8 \mathrm{~V}\) and (ii) \(V_{B}=-1.8 \mathrm{~V}\).

(b) Repeat part (a) for the circuit shown in Figure P2.33(b).
