About this exam

This is a 2023 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) at the Addis Ababa Institute of Technology (AAiT). The exam covers fundamental concepts in signal processing, system analysis, and circuit theory. **Key Topics Covered:** System properties (linearity, time-invariance, memory, causality), state-space representation of circuits, inverse Laplace transforms, convolution integrals, Fourier series representation of waveforms, RMS value calculation, frequency domain analysis, and Fourier transforms of various signals. **Exam Structure & Format:** The exam consists of 6 multi-part analytical problems requiring mathematical derivations and circuit analysis. It is worth 50% of the total course grade with a time allotment of 3 hours.
