In this question, we are asked to show that the positive logic nand gate is the negative of nor gate.
00:08
So first let's write the truth table for the nand gate.
00:12
For the nand gate, the input let's take it as a, b then this will be having the output as a plus b bar.
00:23
So let us take inputs 0, 0, 0, 1, 1, 0 and 1, 1 and this will give us the output as 0 plus 0 is 0 and 0 plus 0 bar is 1, 1 plus 0 is 1 and its bar gives us the value as 0, 1 plus 0 bar gives the value as 0, 1 plus 1 is 1, bar value means 0.
00:54
So this is the nand gate.
00:58
So we are asked to draw the negative nor gate...
