Professor Christos Ferekides of the USF electrical engineering department teaches his Laboratory 1: Circuits course. Electrical engineering students, from left, David Touvell, Justin Mzcrowski and Isabella Delgado are being shown the “pulse trains” on the digital phosphorus oscilloscope, which they have transmitted using signals from a TV remote control.
“Seeing the charactertistics of the signal emitted by the remote control and how your everyday TV remote communicates with other devices is interesting,” said Touvell.
Ferekides explains that the main objective of this lab was to give his students the opportunity to design and implement an experimental procedure given only a list of topics and questions that each lab pair must investigate.
“Working with IR transmitters and receivers and observing their signal characteristics is something everyone has experienced, but just have not realized,” said Delgado. “If you’ve ever put your hand in front of your remote control or have had something blocking your cable box, you’ve witnessed this experiment in a nutshell.” As the second to last lab of the semester in Laboratory 1: Circuits, these electrical engineering students will soon graduate to Laboratory 2: Electronics.
