Design a binary priority encoder as shown in the figure 1

Design of a Binary Priority Encoder as shown in Figure 1 and form all with the NOR and NAND gates. Constructed the
The description of the required encoder is given below (A is MSB):
Normal cases (if only one input is activated):
- if only A is activated (A =0), XY = 00
- if only B is activated (B =0), XY = 01
Encoder
- if only C is activated (C =0), XY = 10
· Output Bits
- if only D is activated (D =0), XY = 11
Abnormal cases (if more than one input is activated):
I
Input Bits -
I
- A has more priority than B
I3
- B has more priority than C
- C has more priority than D
- A has more priority than B,C,D
Figure 1
- B has more priority than C,D
(for example, if both C and D are activated, XY = 10)
• If no input is activated: XY= 00
