The gain differs only from that in Section 5.4.5 in being positive rather
than negative. Thus the magnitude plot is just the mirror image of Figure
5.14 about the 0 dB line. The phase differs from that in Section 5.4.5 in
being positive rather than negative. Thus the phase plot is just the mirror
image of Figure 5.14 about the 0 ~ line. The differences of the true plots
from the asymptote lines is the same as in Tables 5.2 and 5.3.
