Consider two npn transistors as shown in figure. If 0 Volts corresponds to false and 5 Volts correspond to true then the output at C corresponds to :
  1. A NAND B
  2. A OR B
  3. AAND B
  4. ANOR B

Solution

The output at $\mathrm{C}$ corresponds to A NAND $ \mathrm{B} \text { or } \overline{\mathrm{A} \cdot \mathrm{B}}=\mathrm{C} $
