The logic gate for which the output goes 'HIGH' or '1' only when an odd number of 'HIGH' or '1' are at its input, is
Options
- AOR gate
- BNAND gate
- CEx-OR gate
- DNOR gate
Correct answer
C. Ex-OR gate
Step-by-step solution
A logic gate providing a HIGH output exclusively when an odd number of inputs are HIGH can be identified by analyzing standard gate behaviors. The Exclusive-OR (Ex-OR) gate is defined such that for two inputs A and B : output is 1 if either A or B is 1 but not both, corresponding to an odd count (one) of HIGH inputs. For A = 0 , B = 0 , output is 0 (even); A = 0 , B = 1 or A = 1 , B = 0 , output is 1 (odd); A = 1 , B = 1 , output is 0 (even). This characteristic of the Ex-OR gate aligns precisely with the given con
