EXPERIMENTS IN SIGNAL PROCESSING

EMONA ESSB-30

SHOW STUDENTS LAPLACE & z-TRANSFORM MATH IN THE REAL WORLD

The Emona ESSB-30 add-on board for the NI ELVIS III & II/+ enables studentsto patch together continuous time and discrete-time systems in real hardware,for circuit theory, digital signal processing and signals & systems courses.

The Emona ESSB-30 Signal Systems Experimenter for the NIELVIS III and II/+ makes it possible for students toexperience at first hand the interaction between the theoryand mathematics of the digital signal processing, circuitanalysis and signals and systems textbooks, with the realworld of hardware and of signals in wires and waves.

The accompanying 16 experiment Lab Manual coversintroductory level experiments,designed to provide hands on exercisescovering most of the key concepts andchallenges in an undergraduate SignalProcessing and Signals & Systemscourses.

ESSB-30 Lab Manual Experiments:The ESSB-30 experiment manual isdesigned to provide a practical“hands-on”, experiential, lab-based component to thetheoretical work presented in lectures on the topics typicallycovered in introductory signals courses for engineeringstudents.

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 systems

theory, engineering students in general can reinforce theirunderstanding 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” toconsolidate their knowledge of theunderpinning theory, which at times isparticularly abstract and hard to grasp forthese early engineering students. They arenot constrained by the software and needto be systematic in debugging their ownsystems when results do not meet theirexpectations.

The common reaction of early students when confrontedwith “Complex Analysis” is one of confusion and regressionto “rote-learning” in order to survive the examinationprocess. This manual has as its predominant aim to createreal, “hands-on” implementation of the theory, in such away that the 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 ESSB-30 hardware,and lab manual experiments, can easily be integrated or adapted to suit your current signalsand systems courses and text books.

ESSB-30 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 ESSB-30/NI ELVIS bundle. Given that ESSB-30 is by design anopen-ended modeling system it is possible to build many more experiments than is currently documented.
