KPIT Technologies Interview Questions, Process, and Tips

Q1. What is rectifier? what are the different types of rectifier??
Ans. 
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). There are different types of rectifiers including half-wave, full-wave, and bridge rectifiers.
• Rectifier is used to convert AC to DC by allowing current to flow in only one direction.

• Half-wave rectifier only allows one half of the AC waveform to pass through.

• Full-wave rectifier allows both halves of the AC waveform to pass...read more

Q2. What is flip flop? what are the different types of flip flop? Draw circuit diagram and truth table for JK flip flop
Ans. 
A flip flop is a digital circuit that stores a single bit of data. There are different types of flip flops such as SR, D, JK, and T flip flops.
• Flip flop is a sequential logic circuit that stores one bit of data.

• Types of flip flops include SR, D, JK, and T flip flops.

• JK flip flop has two inputs (J and K), a clock input, and two outputs (Q and Q').

• The truth table for a JK flip flop shows the behavior of the flip flop bas

Q1. Find "Fibonacci" series
Ans. 
Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.
• Start with 0 and 1 as the first two numbers in the series

• Add the previous two numbers to get the next number in the series

• Repeat the process to generate the Fibonacci series

Q2. Application of bode plot and nyquist plot
Ans. 
Bode plot and Nyquist plot are used in control systems to analyze the stability and frequency response of a system.
• Bode plot is used to analyze the frequency response of a system by plotting the magnitude and phase of the transfer function against frequency.

• Nyquist plot is used to analyze the stability of a system by plotting the frequency response on a complex plane.

• Bode plot helps in understanding the gain and phase ...read more

Q3. Difference between van neuman and harvard architecture
Ans. 
The main difference between von Neumann and Harvard architecture is the separation of data and instruction memory.
• Von Neumann architecture uses a single memory space for both data and instructions, while Harvard architecture uses separate memory spaces for data and instructions.

• Harvard architecture allows for simultaneous access to data and instructions, leading to potentially faster performance.

• Von Neumann architectur...read more
