Modulation is the process of varying a carrier signal's properties, such as amplitude, frequency, or phase, to transmit information.
Modulation is used in telecommunications to encode information on a carrier signal.
There are different types of modulation, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).
Examples of modulation include AM radio broadcasting, FM radio broadcasting,...
Modulation is the process of varying a carrier signal's properties to transmit information.
Types of modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM)
AM varies the amplitude of the carrier signal based on the input signal
FM varies the frequency of the carrier signal based on the input signal
PM varies the phase of the carrier signal based on the input signal
I applied via Walk-in and was interviewed in Sep 2023. There were 4 interview rounds.
Lists are mutable, ordered collections of items, while tuples are immutable, ordered collections. Dictionaries are key-value pairs.
Lists are denoted by square brackets [], tuples by parentheses (), and dictionaries by curly braces {}.
Lists can be modified after creation, while tuples cannot be changed once created.
Dictionaries store data in key-value pairs, allowing for quick lookups based on keys.
Example: list = [1, 2...
A class is a blueprint for creating objects, while an object is an instance of a class. Classes define the properties and behaviors of objects.
A class is a template for creating objects with similar properties and behaviors
An object is an instance of a class, created using the class blueprint
Classes can have attributes (variables) and methods (functions)
Objects can interact with each other by calling methods on each ot...

Sampling theorem states that a continuous signal can be accurately represented by discrete samples if the sampling rate is at least twice the highest frequency component of the signal.
Sampling theorem is also known as Nyquist-Shannon sampling theorem.
It is used in digital signal processing to convert analog signals into digital signals.
According to the theorem, the sampling rate must be at least twice the frequency of ...

Nyquist plot is a graphical representation of a system's frequency response in the complex plane.
Nyquist plot shows how a system responds to sinusoidal inputs at different frequencies.
It plots the real part of the transfer function against the imaginary part.
The plot can help analyze stability and performance of control systems.
A Nyquist plot can be used to determine the stability of a system by looking at the encircle...
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.
It helps in understanding the relationship between voltage, current, and resistance in an electrical circuit.
It is named after the German phys...
