The Emona SIGEx-311 add-on board for the NI ELVIS II/+ enables students topatch together continuous time and discrete-time systems in real hardware,for circuit theory, digital signal processing and signals & systems courses.The Emona SIGEx-311 Signal Systems Experimenter for NIELVIS II/+ makes it possible for students to experience atfirst hand the interaction between the theory andmathematics of the digital signal processing, circuit analysisand signals and systems textbooks, with the real world ofhardware and of signals in wires and waves.
The accompanying 16 experiment Lab Manual coversintroductory level experiments, designedto provide hands on exercises coveringmost of the key concepts and challengesin an undergraduate Signal Processingand Signals & Systems courses.
SIGEx-311 Lab Manual Experiments
The SIGEx experiment manual is designedto provide a practical “hands-on”,experiential, lab-based component to thetheoretical work presented in lectures onthe topics typically covered in introductory signals coursesfor engineering students.
Whilst the experiments are predominantly focused on allelectrical engineering students, this material is not only forelectrical engineers. With an understanding of differentialequations, algebra of complex numbers and basic systemstheory, engineering students in general can reinforce their
understanding of these important foundational principlesthrough practical laboratory course work where they see the“math come alive” in real circuit based signals. Thisprovides a foundation for further study of communications,control, and systems engineering in general.
Students take responsibility for the construction of theexperiments and “learning by doing” to consolidate their
knowledge of the underpinning theory,which at times is particularly abstract andhard to grasp for these early engineeringstudents. They are not constrained by thesoftware and need to be systematic indebugging their own systems when resultsdo not meet their expectations.
The common reaction of early studentswhen confronted with “Complex Analysis”is one of confusion and regression to
“rote-learning” in order to survive the examination process.This manual has as its predominant aim to create real,“hands-on” implementation of the theory, in such a way thatthe student can directly articulate and connect themathematical abstractions with real world implementations.It is a journey of personal discovery where the motto is“why is it so ?”
Students implement experiments by patching together functional blocks - such as samplers,filters, independent adders, integrators, unit delays, etc. Therefore, the SIGEx-311 hardware,and lab manual experiments, can easily be integrated or adapted to suit your current signalsand systems courses and text books. * Volume 2 to be released in due course.

SIGEx Experiments-to-Textbooks ComparisonThis table aims to direct users to sections of commonly available text books which contain theory and exercises related toexperiments currently documented and implemented with the SIGEx/NI ELVIS bundle. Given that SIGEx is by design anopen-ended modeling system it is possible to build many more experiments than is currently documented.
ERRORS and OMISSIONS EXCEPTED. The above comparison table is intended as an approximate guide and does not imply endorsement of the authors or publishers.
