Paper ID #27852Laboratory Course Development for Biomedical Signals and SystemsProf. Benjamin Hawkins, Cal Poly, SLO My professional interests focus on the development and use of microsystems (biosensors, microcon- trollers, etc) to matters of human health. Primarily this is focused on microfluidics, but also ranges from wearable devices to laboratory equipment. Applications range from cell measurements to ecological ques- tions. Educationally, I am focused on developing courses and content that connects theory to technology in practice, with an emphasis on rigorous understanding of both.Dr. James Eason, Cal Poly San Luis

Martin Department of Chemical Engineering University of ArkansasIntroductionAmerican Society for Engineering Education data show that engineering enrollment in U.S.universities has increased by more than 50% over the last ten years, while the number ofengineering faculty has increased by only 15% over the same time period (Yoder 2009, 2017).As a result, the average number of students in engineering classrooms has steadily increased, andthis increase has occurred at a time when our students enter the classroom with far lessexperience in the

LaboratoryIntroductionTraditional undergraduate communications courses have focused on analog transmissionschemes such as amplitude (AM) and frequency modulation (FM). Given the comparativelysimple design of analog modulation circuitry, offering a laboratory component to the course isstraightforward. In a typical laboratory session, students could construct and investigate theperformance of AM or FM transmitters or receivers.With the emergence of technology such as digital cellular telephony and wireline and wirelessdata communications, the emphasis has shifted from analog to digital modulation. Because ofthis shift, digital communications has become an important component to all levels ofcommunications instruction. Due to the complexity of equipment that can emulate
