Design Simulation Capability
A powerful feature of PAC-Designer is its simulation
capability, enabling quick and accurate verification of
circuit operation and performance. Once a circuit is
configured via the interactive design process, gain and
phase response between any input and output can then
be determined. This function is part of the simulator
capability which derives a transfer equation between the
two points and then sweeps it over the user-specified
frequency range. Figure 3 shows a typical screen plot of
the gain/phase simulator. In it are the input to output
response curves of an Elliptical and a Butterworth re-
sponse stored in configuration A and B respectively.
These are the two options specified in the design screen
window shown in Figure 2.
The simulator is capable of displaying up to four separate
input to output responses. This allows multiple signals to
be viewed as well as intermediate results of component
changes so performance comparisons can be made.
There is also a user-positioned crosshair cursor that
intersects the curves on the plot, and reads out the gain
and frequency in the lower right hand corner of the plot
window when activated.
