The circuit was solved and the results are shown in Table 12.5, to-
gether with SPICE simulation results. To ensure that the second-order
harmonic components are free of numerical errors, several SPICE simula-
tions with different step sizes used in transient analysis were conducted.
The absolute errors between the harmonic components obtained from
using different step sizes in transient analysis are less than 0.2 decibels.
It is seen that the method gives good prediction of both the funda-
mental and the second-order harmonic components. The second-order
