Objectives

Students are introduced to the basic of Electronics.

Since some of the students did not have any exposition to Electric Circuits Theory, an introduction is required.

The prevalent idea is to prepare students for the subsequent disciplines in Electronics and Instrumentation, giving them a solid background in the basics of diodes, bipolar junction transistors  and field effect transistors. An introduction to Operational Amplifiers is also covered. Being a subject for Biomedical Engineering an emphasis is put on circuits involving bio-signals amplifiers.

Patient electric safety is introduced

Prerequisites

Students are required to have a background in college calculus and electromagnetics.
