1. Create a 4-1 MUX using ONLY tri-state buffers and inverters in LogicWorks. This circuit will select one output from four inputs based on two addition switches. Please read textbook page 140 section 3-7 Multiplexers before implementing this lab assignment. You can test out your circuit using binary switches and a Hex keyboard (use Ctrl-F to show signal values). Please read Page 140 for detailed information about MUX (Multiplexer). a. This MUX should have two selector lines SO and S1 and four input lines A-D. b. The output should match the following table: Si SO I OUTPUT 0 0 A 0 1 || B 1 0 C 1 1 D In other words, when SO and S1 are both zero the MUX will select input A for use as the output
