Question

After completing a design and fabrication of digital system, a designer finds that one more inverter is required. However the only spare gates in the system are 3 input or, a 2 input and, and a 2 input xor. How should the designer realize the inverter function without adding another ic.

Answer 1

After completing the design and fabrication of an SSI-based digital system, a designer finds that one more inverter is required

Answer 2

Answer:

just use two input xor gate

Explanation

to make an inverter make one input to xor high and then it will act as inverter for second input. For ex if one input of xor is a level 1 then if you pass 0 to other input it will give 1(inverted) or if you pass 0 it will give 1(inverted) since 0^1=1 and 1^1=0
