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

Complete the truth table for the modified selector.

Thats the truth table and circuit for the previous

Table 2: 2 to 4 One-Hot Decoder with Active-Low Enable Truth Table

E	B	A	Y0	Y1	Y2	Y3

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

Y0 =

Y1 =

Y2 =

Y3 =

Using the new equations, alter the circuit and hierarchal block from the previous task to include an active low enable.

If possible please leave explainations

DECODERS Lab Instructions | Task 4 For this task using decoders, we will be designing and implementing a 2 to 4 One-Hot, Active Low Decoder. For this first task, we will not be including the enable line shown in the block diagram Using your knowledge of logic design and the block diagram provided, complete the truth table for the 2 to 4 Decoder. 1. Table 1: 4:1 Active-Low Selector Truth Table Y3 0 0 0 Y1 Y2 0 YO 0 0 0 0 0 0 2. Using the truth table, generate the Boolean equation for the output. Y1 B'A Y3 BA
