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...read more

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...read more

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...read more

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...read more

Sampling theorem states that a continuous signal can be perfectly reconstructed from its samples if the sampling rate is greater than twice the highest frequency component of the signal.

• Sampling theorem, also known as Nyquist-Shannon theorem, is essential in digital signal processing.

• It states that in order to accurately reconstruct a continuous signal from its samples, the sampling rate must be at least twice the high...read more

AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction only.

• AC stands for Alternating Current while DC stands for Direct Current

• AC changes direction periodically while DC flows in one direction only

• AC is used for power transmission over long distances while DC is used for electronic devices

• AC voltage can be easily stepped up or down using transformers while DC v...read more

Power factor is the ratio of real power to apparent power in an AC circuit.

• It measures how efficiently electrical power is being used.

• A power factor of 1 means all the power is being used effectively.

• A power factor less than 1 means some power is being wasted.

• Inductive loads like motors have a lagging power factor while capacitive loads have a leading power factor.
