Circuit Specs

Depending on the circuit problem type, some circuit generation options may lead to awkward results that would be of no practical utility for students. For instance, consider the determination of the natural frequencies of a second or higher order circuit. If symbolic element values are selected, the expression of the natural frequencies may be very complicated. The same difficulties arise when computing the transient solution via Laplace transform inversion or when solving AC circuits using phasors. In order to avoid overly complicated results, symbolic circuit elements may be disabled and/or overridden by the circuit generation engine. The table below provides a complete list of circuit problems for which symbolic elements can be used, depending on the problem difficulty.
