Question 12.15: Calculate the second harmonic distortion if an output wavefo...

Using Eq. (12.34),

D_{2}=\left|\frac{\frac{1}{2}\left(V_{C E_{\max }}+V_{C E_{\min }}\right)-V_{C E_{Q}}}{V_{C E_{\max }}-V_{C E_{\min }}}\right| \times 100 \%                                (12.34)

we get

a.  D_{2}=\left|\frac{\frac{1}{2}(22 V +1 V )-12 V }{22 V -1 V }\right| \times 100 \%= 2 . 3 8 \%

b.    D_{2}=\left|\frac{\frac{1}{2}(20 V +4 V )-12 V }{20 V -4 V }\right| \times 100 \%= 0 \%                              (no distortion)
