Symbolic circuit analysis

Symbolic circuit analysis is a formal technique of <a href="/facts/Circuit_analysis/IjmVqbG8">circuit analysis</a> to calculate the behaviour or characteristic of an electric/electronic circuit with the independent variables (time or frequency), the dependent variables (voltages and currents), and (some or all of) the circuit elements represented by symbols.
When analysing electric/electronic circuits, we may ask two types of questions: What is the value of certain circuit variable (<a href="/facts/Voltage/EN2po6N2">voltage</a>, <a href="/facts/Current_(electricity)/Dc1xdnUX">current</a>, <a href="/facts/Resistance_(electricity)/hxSt0UAj">resistance</a>, <a href="/facts/Gain_(electronics)/CWbehg27">gain</a>, etc.) or what is the relationship between some circuit variables or between a circuit variable and circuit components and frequency (or time). Such relationship may take the form of a graph, where numerical values of a circuit variable are plotted versus frequency or component value (the most common example would be a plot of the magnitude of a transfer function vs. frequency).
Symbolic circuit analysis is concerned with obtaining those relationships in symbolic form, i.e., in the form of <a href="/facts/Analytical_expression/y0xCXlSk">analytical expression</a>, where the complex frequency (or time) and some or all of the circuit components are represented by symbols.
