+<p>
+  This example demonstrates a half-wave rectifier. The diode allows current to
+  flow in only one direction, effectively cutting off the negative portion of
+  the AC input sine wave. The two voltage probes allow for a comparison of
+  the input and output waveforms.

+  The simulation graph shows the input sine wave and the rectified output.
+  The output voltage follows the positive half of the input sine wave and is
+  approximately 0V during the negative half, demonstrating the rectifying
+  action of the diode.
