This complete 3-volume lab manual offers hands-on labs for teaching basic analog and digital communication topics such as AM, FM, SNR Concepts, sampling, TDM, and delta-sigma modulation. The Emona DATEx Add-on Board combines with the NI ELVIS platform, providing a foundation to assist the student in visualizing and better understanding the concepts. In this lab students will become familiar with the block diagrams and the modules on the EMONA Communication Board that are used for building communication systems. They will also learn how to use the various NI ELVIS III instruments to generate signals and take measurements. Emona Celebrating 10+ years partnership with NI. Emona is celebrating our 10+ years of partnership with National Instruments, for whom we make a number of very successful add-on boards for the NI ELVIS platform, now also in its 3rd edition as NI ELVIS III. Pictured is receiving the plaque from National Instruments READ MORE.

A unique hands-on approach to help students understand this abstract topic, bringing theory and application together in the lab

How does SIGEx help students understand “Signals & Systems” & signal processing theory better?

The EMONA SIGEx board and comprehensive Lab Manual and closely follows the typical curriculum encountered by engineering students and is based on leading textbooks on this topic. By having hands-on modules which students patch together according to the block diagram in the lab, students can build actual working implementations of the theoretical structures they are studying. This enhances their understanding and reduces the number of students who “just don’t get it”. Every theoretical topic has an equivalent lab implementation so students can see the “maths come alive” in the lab.
