Multiplexers and Demultiplexers

Multiplexers and Demultiplexers online, interactive lab
In this lab, students will learn how multiplexers and demultiplexers work, as well as the basics of clock multiplexing. While using Multisim and NI ELVIS to simulate circuits and deploy them to the FPGA on the DSDB board, students will reflect on the similarities and differences between encoders and multiplexers, examine the function of a basic 2-to-1 Multiplexer using logic gates, and observe the behavior of clock multiplexing using an oscilloscope. The lab is hosted on the interactive, online learning platform, Thinkscape.
