- Q1. 1. Why are nand and not are Are called as universal gates Explain
- Ans.
NAND and NOR gates are called universal gates because they can be used to create any other type of logic gate.
NAND gate can be used to create AND, OR, and NOT gates by combining multiple NAND gates
NOR gate can be used to create AND, OR, and NOT gates by combining multiple NOR gates
Using De Morgan's theorem, NAND and NOR gates can be used interchangeably to implement any logic function
- Q2. 2. Explain about Ring and Johnson counter
- Ans.
Ring and Johnson counters are types of shift registers used in digital electronics for counting purposes.
Ring counter is a type of shift register where the output of the last flip-flop is connected to the input of the first flip-flop, creating a ring-like structure.
Johnson counter is a type of shift register where the output of the last flip-flop is connected to the input of the first flip-flop through an XOR gate, cre...

I applied via Campus Placement and was interviewed in Jan 2016. There were 3 interview rounds.
Interview Questionnaire
5 Questions
- Q1. Reduction of 3D Kmap ?
- Ans.
Reduction of 3D Kmap involves simplifying a 3D truth table to minimize the number of logic gates required.
3D Kmap is a graphical representation of a truth table with three variables
Reduction involves grouping adjacent cells with the same output value
The goal is to minimize the number of groups and variables in each group
Simplification can be done using Boolean algebra or Karnaugh maps
Example: Reducing a 3D Kmap with in
