Q2. Diffrential amplifier sum
Ans. 
A differential amplifier sums the difference between two input voltages multiplied by a constant gain.
• Differential amplifiers amplify the voltage difference between two input signals while rejecting any common-mode signals.

• They are commonly used in instrumentation amplifiers, audio amplifiers, and operational amplifiers.

• The gain of a differential amplifier is determined by the ratio of the resistors in the circuit.

Q3. Diff between bjt,igbt,bjt,mos
Ans. 
BJT, IGBT, BJT, and MOS are all types of transistors with different structures and characteristics.
• BJT (Bipolar Junction Transistor) is a current-controlled device with high switching speed.

• IGBT (Insulated Gate Bipolar Transistor) combines the advantages of MOSFET and BJT, used in high power applications.

• MOS (Metal-Oxide-Semiconductor) transistors are voltage-controlled devices with low power consumption.

• Each type of t...read more

The aptitude test is beneficial and somewhat easy.

The coding test was both successful and somewhat challenging.

Group discussions are highly beneficial.

Q1. What is the concept of Object-Oriented Programming (OOP) in Python?
Ans. 
Object-Oriented Programming (OOP) in Python is a programming paradigm based on objects and classes to structure code effectively.
• Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: class Dog with attributes and methods.

• Inheritance: Mechanism to create a new class using properties of an existing class. Example: class Bulldog inherits from class Dog.

• Polymorphism: Ability to...read more

Q2. What can you tell me about machine learning algorithms?
Ans. 
Machine learning algorithms enable computers to learn from data and make predictions or decisions without explicit programming.
• Supervised Learning: Algorithms learn from labeled data. Example: Linear Regression for predicting house prices.

• Unsupervised Learning: Algorithms identify patterns in unlabeled data. Example: K-Means Clustering for customer segmentation.

• Reinforcement Learning: Algorithms learn by interacting wi...read more
