This circuit serves to show how 4 diodes can be used in order to create a fully rectified sine wave. Please note that the starting frequency of 50 Hz is quite slow and thus the results of this rectification may not be cleary seen at first. You may increase the frequency to get a better idea of how the sine wave would look but I personally left it at 50 Hz just to show how the sine wave behaves as the initially AC input tends to zero. Also bear in mind that this wave is not smoothed and would thus make for a poor DC input regardless of its rectification. I will post a circuit which utilizes smoothing capacitors at a later date.
