सही विकल्प 3 है। 

अवधारणा:

NAND द्वार

प्रतीक:

सत्यमान सारणी:

निवेश A

निवेश B

निर्गम 

0

0

1

0

1

1

1

0

1

1

1

0

 

निर्गम समीकरण

प्रमुख बिंदु:

1) यदि A हमेशा उच्च होता है, तो निर्गम अन्य निवेश B का उल्टा मान होता है, अर्थात B̅

2) निर्गम कम तभी होता है जब दोनों निवेश अधिक हों

3) यह एक सार्वभौमिक द्वार है

A

B

EXOR

EXNOR

NAND

NOR

जब सत्यमान सारणी से A = B = 0, NAND और NOR गेट के लिए निर्गम Y = 1

साथ ही जब A = B = 1, NAND और NOR द्वार के लिए निर्गम Y = 0
