Biomeasurements Lab

BME 22400/ 1 Cr.

Laboratory exercises will reinforce the foundations of basic circuit theory. Electronic instruments are used in the context of biomedical signal measurement and processing and include the use of oscilloscopes, function generators, transducers, electrodes, biopotential amplifiers and digital data collection and analysis. Laboratory exercises utilize industrially relevant instruments for measurement and acquisition of time varying signals arising from electronic and bioelectric sources.

Outcomes

Upon completion of the course, students will be able to:

• Solve problems using basic principles, conventions, and procedures involving voltages, currents, and power. [1]
• Perform basic measurements of voltages and currents in electric circuits using basic laboratory measurement equipment including oscilloscopes, function generators and digital multi-meters. [6]
• Design, assemble, and test circuits that demonstrate basic circuit laws and op-amp applications. [6]
• Demonstrate basic skills using a generic digital data acquisition system. [6]
• Demonstrate basic skills in Matlab for both the solution of circuit analysis problems but also processing of data acquired using a digital data acquisition system. [6]
• Collect data from experiments and write a full lab report demonstrating both an understanding of the assignments and evidence of collaborative team work. [3, 5]
