Digital Electronics MCQ Level- 1 - Physics MCQ

From the waveform A, B and C, it is clear that output is 1, if both B and A are 1 otherwise zero.
C = A ^. B
The correct answer is: AND gate

The correct answer is: 

NOT gate implies output  where A is the input.
The correct answer is: 01011

The correct answer is: 

Equivalent circuit is


The correct answer is:  

Hexadecimal is written with 16 numbers starting from 0, i.e., 0, 1,2, 3,...14, 15. The number 10 → A; 11 → B; 12 → C; 13 → D; 14 → E; 15 → F in place of two digits. To convert binary number in hexadecimal make the pairs of four numbers starting from right. Then convert them in decimal then hexadecimal e.g. (110000111101)₂  ⇔ [(1100) (0011) (1101)₂] in binary number ⇔ [(12) (3) (13) ] in decimal
= C3D is the equivalent hexadecimal number
The correct answer is: C3D

NAND implies 
The correct answer is: NAND

⇒ AND gate implies Y=A^.B.
The correct answer is: AND

From the response of A, B and C, it is clear that C = A^.B, hence, an AND gate.
The correct answer is: AND gate

NAND gate is given as 
The correct answer is:
