Q1. Difference between diode and transistor
Ans. 
A diode is a two-terminal electronic component that allows current to flow in one direction only, while a transistor is a three-terminal electronic component that can amplify or switch electronic signals.
• Diode has two terminals, anode and cathode, and allows current to flow in one direction only

• Transistor has three terminals, base, emitter, and collector, and can amplify or switch electronic signals

• Diodes are used in r...read more

Q1. What is modulation
Ans. 
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,...read more

Q2. Types of modulation
Ans. 
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

Q3. Difference between list and tuple dict
Ans. 
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

Q1. What is class,object,differnece
Ans. 
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

Q1. What is sampling theorem
Ans. 
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 ...read more
