What do you mean by Circuit Analysis Techniques?

One simplifying technique often used in complex circuit problems is that of breaking the circuit into pieces of manageable size and analyzing individually the pieces that may be already familiar. Equivalent circuits are introduced which utilize Thévenin's and Norton's theorems to replace a voltage source by a current source or vice versa.Nodal and loop analysismethods are then presented. Later the principles of superposition and linearity are discussed.Also, wye-delta transformation is put forth as a tool for network reduction. Finally, computer-aided circuit analyseswith SPICE andMATLAB are introduced.
