About this exam

This is a 2022 final exam paper for signal-and-system-analysis at aau (electrical-computer-engineering). This is a final examination for the Signal and System Analysis course (ECEG 2141) administered by the Addis Ababa Institute of Technology. The exam evaluates students' proficiency in circuit analysis using advanced mathematical techniques. **Key Topics Covered:** Laplace transform methods for circuit analysis, state-space representation of electrical networks, matrix form of state equations, computation of matrix exponentials (e^At), and determination of impulse response for RC circuits. **Exam Structure & Format:** The exam is a 3-hour assessment worth 50% of the course grade. It consists of analytical problems requiring the derivation of state equations, application of Laplace transforms to solve for time-domain currents and voltages, and calculation of system responses.
