Question:
Modulo-2 adder (without carry-out) works like
Modulo-2 adder (without carry-out) works like
Show Hint
XOR operation is commonly called modulo-2 addition.
Updated On: Jun 25, 2026
- OR gate
- XOR gate
- XNOR gate
- XNAND gate
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Modulo-2 addition follows the rule
\[
0+0=0
\]
\[
0+1=1
\]
\[
1+0=1
\]
\[
1+1=0
\]
Step 1: Construct truth table.
The output pattern becomes \[ 0,1,1,0 \]
Step 2: Compare with logic gates.
The XOR gate has exactly the same truth table.
Step 3: Conclusion.
\[ \boxed{\text{Modulo-2 Adder = XOR Gate}} \]
