ESP1104 - Introduction to Electronic Systems

I
n this module students learn fundamental principles essential to the design and use of electronic circuits for a variety of different disciplines. Particular emphasis will be given to circuits that are used in research and development, such as sensor amplifiers, filters, and data-acquisition. The module has both analog and digital circuit principles, and involves hands-on construction and testing of circuits during practical sessions that are correlated to tutorial questions.
