Question 88: Semiconductors and Logic Gates

Question

In the circuit, the logical value of $$A=1$$ or $$B=1$$ when potential at $$A$$ or $$B$$ is $$5 \mathrm{~V}$$ and the logical value of $$A=0$$ or $$B=0$$ when potential at $$A$$ or $$B$$ is $$0 \mathrm{~V}$$.
The truth table of the given circuit will be :

Accepted Answer

Given circuit is equivalent to an AND gate.
$$	herefore$$ $$\matrix{
   A & B & Y  \cr 
   0 & 0 & 0  \cr 
   0 & 1 & 0  \cr 
   1 & 0 & 0  \cr 
   1 & 1 & 1  \cr

} $$

Answer

$$\matrix{
   A & B & Y  \cr 
   0 & 0 & 0  \cr 
   1 & 0 & 0  \cr 
   0 & 1 & 0  \cr 
   1 & 1 & 1  \cr

} $$

Answer

$$\matrix{
   A & B & Y  \cr 
   0 & 0 & 0  \cr 
   1 & 0 & 1  \cr 
   0 & 1 & 1  \cr
