# ECE 2024 Circuits and Devices

In electrical and computer engineering, we are primarily interested in two things: electrical signal and electrical energy. For electrical signal, we want to study how we can gather, store, process, transport, and present the information. For example, in computer engineering, we want to process and store information digitally; in communication system, we study how we can process and transport information. For electrical energy, we want to study how we can generate, distribute, store and convert energy of various forms. We have power system major that studies how to generate, distribute electrical energy in an efficient way; we also have power electronics that convert electrical energy in different forms. For all of these technology to happen, we need circuits and devices. In this class, we are covering DC and AC circuit analysis, transient response of RLC circuits, frequency response of circuits and many more; in the second part of the class, we introduces some basic electrical devices such as operational amplifier, diodes, transistors(BJT and MOSFET). In this module, you can find my lecture slides, practice problems, and some labs.
