A diode is a nonlinear circuit element with circuit symbol and (ideal) \( v-i \) characteristic shown below \[ +\frac{v_{D}(t)}{\dot{l}_{D}(t)}-i_{D}(t) \] Part (a): This figure shows a half-wave rectificr circuit. If the source voltage, \( v_{S}(t) \), is a sinusoid of amplitude \( \mathrm{A} \) and radian frequency \( \omega \), i.c. \( v_{S}(t)-A \sin (\omega t) \), sketch the voltage \( v_{n}(t) \). Part (b): This figure shows a full-wave rectifier circuit. With the same sinusoidal \( v_{S}(t) \) again sketch the voltage \( v_{n}(t) \).
