Signals, instruments and systems

Summary

The goal of this course is to transmit knowledge in sensing, computing, communicating, and actuating for programmable field instruments and, more generally, embedded systems. The student will be able to put in practice the knowledge acquired using concrete software and hardware tools.

Learning Outcomes

By the end of the course, the student must be able to:

• Estimate environmental monitoring system requirements (communication, sensing, actuation, computation)
• Develop software for an embedded system/instrument
• Analyze signals in time and frequency domain
• Analyze C/Matlab/Python program outputs
• Implement C/Matlab/Python code
• Compute direct and inverse Fourier Transforms
• Analyze constraints and resources of an embedded system/instrument
• Conduct systematic experiments and system performance evaluation
• Design digital filters
• Design control algorithms
• Design localization algorithms
• Design simple control algorithms

Transversal skills

• Plan and carry out activities in a way which makes optimal use of available time and other resources.
• Write a scientific or technical report.
• Access and evaluate appropriate sources of information.
• Collect data.
• Evaluate one's own performance in the team, receive and respond appropriately to feedback.
• Assess progress against the plan, and adapt the plan as appropriate.
• Identify the different roles that are involved in well-functioning teams and assume different roles, including leadership roles.
• Manage priorities.
• Make an oral presentation.
• Use both general and domain specific IT resources and tools
