Half Wave Rectification (Part 2)

Solution:

(a) In this situation the diode will conduct during the negative part of the input as shown in Fig. 2.49, and  will appear as shown in the same figure. For the full

period, the dc level is

The negative sign indicates that the polarity of the output is opposite to the defined polarity of Fig. 2.48.

Fig 2.49: Resulting  for the circuit of Example.

(b) Using a silicon diode, the output has the appearance of Fig. 2.50 and

This is a difference that can certainly be ignored for most applications. For part c the offset and drop in amplitude due to VT would not be discernible on a typical oscilloscope if the full pattern is displayed.
