Fourband Filter Optimization
Optimization Results
The optimization was performed on a 32-bit Linux machine and the results generated during the
optimization process are shown in Table 13-10:
The minimum and maximum errors give the range of the residuals (difference between the
target and the measured values) after optimization. The global error represents the error
function minimized by the optimizer (this value may differ with the merit function of the
optimizer).
In Figure 13-21 the optimized response was not plotted since the target and the output responses
were the same.
Modified Initial Values
Table 13-10. Values Extracted from fourband.otm File
Minimum Error Global Error Maximum Error
Test 1 1.7×10 −6 1.6×10 −6 7.3×10 −3
Test 2 1.4×10 −4 1.2×10 −2 4.3×10 −1
Now consider the following modified initial values of the capacitors CT, CLC and CPASS:
.PARAM CT=0.002U CLC=0.0001U CPASS=1.0U
The corresponding response is plotted in Figure 13-22.
Figure 13-22. Optimized Response
The minimum and maximum errors are stored in Table 13-10.
