Description: I taught the block course Signals and Systems at Ashesi University in Ghana in February 2026 as part of the Ashesi-ETH Master in Mechatronic Engineering, an ETH4D partnership between ETH Zurich and Ashesi University that trains engineers for sustainable industrial development in sub-Saharan Africa.

Learning Objective

Students learned to represent, analyze, and manipulate discrete-time signals and systems, and to understand how physical systems respond to input signals. The course emphasized using signal excitation and frequency-domain tools to characterize system behavior and identify basic system properties.

Content

Discrete-time signals and systems; Fourier and z-transforms; frequency-domain characterization of signals and systems; system identification; time-series analysis; and filter design.
