For this task, we will be modifying the selector above to include an active-low enable.

Complete the truth table for the modified selector.

Table 2: 4:1 Active-High Selector with Active-Low Enable Truth Table

E	S1	S0	O0

Modify the equations to represent the addition of the active-low enable to the multiplexer.

O₀ =

Using the new equations, alter the circuit and hierarchal block from task 1 to include an active low enable. Once your design is completed, compile, test and verify it on the Basys3 board against the truth table. Make sure to take a screenshot of the circuit for your report.

Here is information on the last selector, I could be wrong so please give it a quick lookover and make sure it looks right before spending your time answering. Thank you
