Question:

For F = A XOR B XOR C with inputs A = 1, B = 0, C = 1, what is the value of F? / F = A XOR B XOR C हेतु इनपुट A = 1, B = 0, C = 1 पर F का मान क्या है?

1.
1 / 1
2.
X (don't care) / X (डोंट केयर)
3.
0 / 0
4.
Z (high impedance) / Z (उच्च प्रतिबाधा)

Correct Answer: 0 / 0

A 3-input XOR outputs 1 when an odd number of inputs are 1 (odd parity). Here two inputs are 1, which is even, so F = 0. Equivalently, (1 XOR 0) XOR 1 = 1 XOR 1 = 0. / 3-इनपुट XOR विषम संख्या में 1 होने पर 1 देता है; यहाँ दो 1 हैं (सम), अतः F = 0।
