Signals and Systems, Part 1 — IITBombayX — January 15, 2015  
We encounter signals and systems extensively in our day-to-day lives, from making a phone call, listening to a song, editing photos, manipulating audio files, using speech recognition softwares like Siri and Google now, to taking EEGs, ECGs and X-Ray images. This course provides the basic toolkit for any signal processing application – the abstraction of signals and systems. 

Circuits and Electronics  — MITx — January 20, 2015 
Learn the fundamentals of electrical circuits and circuit analysis in this session of edX’s first ever course taught by Anant Agarwal. Cover topics like resistive elements and networks, independent and dependent sources, switches and MOS transistors, digital abstraction, dynamics of first- and second-order networks, and analog and digital circuits and applications.

Electronic Interfaces: Bridging the Physical and Digital Worlds — UC BerkeleyX — January 20, 2015
Learn by doing: analyze, design, and build electronic interfaces between sensors and a microcontroller to build a robot or your own creation in this hands-on lab course.  We start with essential theory and develop an understanding of the building blocks of electronics as we analyze, design, and build different parts of a robot from scratch.

Embedded Systems – Shape The World — UT AustinX — January 21, 2015
How do they do it? If that is your reaction every time you see an electronic gadget you like, then wonder no more. Join us on a journey that will unravel how these electronic gadgets are designed, developed, and built as embedded systems that shape the world. We have enhanced the class since the first version concluded in May 2014. This second version will include additional teaching material for Finite State Machines and more.

Discrete-Time Signal Processing — MITx — February 2, 2015
The course begins with a review and extension of the basics of signal processing including a discussion of group delay and minimum-phase systems, and the use of discrete-time (DT) systems for processing of continuous-time (CT) signals.

Symmetry, Structure, and Tensor Properties of Materials — MITx — February 10, 2015
An upper-level undergraduate engineering course that explores the structure and symmetry of materials and the profound effect that structure has on physical properties of materials. Topics include lattices, point groups, and space groups in both two and three dimensions and more.
