In the following circuit, the correct relation between output Y and inputs A and B will be
Options
- AY = A · B
- BY = A + B
- CY = A · B
- DY = A + B
Correct answer
C. Y = A · B
Step-by-step solution
When both of the inputs are given with + 10   V that is logical 1 , both of the diodes are in OFF condition and hence supply voltage will appear at the base terminal of the transistor which makes it switched ON and supply voltage gets a path to the ground through this transistors. Therefore, it represents NAND gate. Hence, Y = A · B
