or 
) and 
is the output voltage then the two gates represented in the following circuit
A
and AND and OR Gate
B
are: - 
OR and NOT Gate
OR and NOT Gate
C
NAND and NOR Gate
D
AND and NOT Gate
Text Solution
Verified by ExpertsThe correct answer is:
B
If 
, there is no potential anywhere here 
If 
, Diode 
is forward biased, here 
If 
, Diode 
is forward biased hence 
If 
, Both diodes are forward biased hence 
Truth table for I 
A | B | Output |
0 | 0 | 0 |
0 | 1 | 1 |
1 | 0 | 1 |
1 | 1 | 1 |
For II 
circuit
When 
junction is unbiased there is no current through it
When 
junction is forward biased
