Q3. What are the types of modulations?

Ans.

Modulation is the process of varying a carrier signal in order to transmit information.

  • Amplitude Modulation (AM) - varying the amplitude of the carrier signal

  • Frequency Modulation (FM) - varying the frequency of the carrier signal

  • Phase Modulation (PM) - varying the phase of the carrier signal

  • Quadrature Amplitude Modulation (QAM) - combining amplitude and phase modulation

  • Pulse Amplitude Modulation (PAM) - varying the amplitude of discrete pulses

  • Pulse Width Modulation (PWM) - va...read more

Q4. How to remove elements from list?

Ans.

To remove elements from a list, use the remove() method or list comprehension.

  • Use the remove() method to remove a specific element from the list.

  • Use list comprehension to remove multiple elements based on a condition.

Q5. Digital Circuits , how do they work ?

Ans.

Digital circuits are electronic circuits that operate using digital signals (0s and 1s) to perform logical operations.

  • Digital circuits use logic gates to process binary information.

  • They can perform operations such as AND, OR, NOT, and XOR.

  • These circuits are the building blocks of computers and other digital devices.

  • Examples of digital circuits include flip-flops, registers, and arithmetic logic units.

Q6. 1. What is wireless communication?

Ans.

Wireless communication refers to the transmission of information without the use of physical connections or wires.

  • Wireless communication allows devices to communicate with each other over a distance using electromagnetic waves.

  • It enables the transfer of data, voice, and video signals wirelessly.

  • Examples of wireless communication technologies include Wi-Fi, Bluetooth, cellular networks, satellite communication, and radio frequency identification (RFID).

Q7. How do Logic gates work ?

Ans.

Logic gates are electronic devices that perform logical operations based on input signals.

  • Logic gates take input signals and produce an output signal based on a specific logic function.

  • They can perform operations such as AND, OR, NOT, NAND, NOR, XOR, and XNOR.

  • For example, an AND gate outputs a high signal only when both input signals are high.

  • A NOT gate inverts the input signal, producing a high output when the input is low.

  • Logic gates are the building blocks of digital circu...read more

Q8. 1. What is Telecommunication?

Ans.

Telecommunication is the transmission of information over a distance using electronic means.

  • Telecommunication involves the exchange of information between two or more parties.

  • It uses various technologies such as telephones, radios, television, and the internet.

  • Telecommunication enables real-time communication, allowing people to connect and communicate regardless of their physical location.

  • Examples of telecommunication include making phone calls, sending text messages, video ...read more

Q9. Difference between queue and stack

Ans.

A queue is a data structure that follows the FIFO (First-In-First-Out) principle, while a stack follows the LIFO (Last-In-First-Out) principle.

  • Queue: Elements are added at the rear and removed from the front.

  • Stack: Elements are added and removed from the top.

  • Queue is like a line of people waiting for a bus, while a stack is like a stack of plates.

  • Queue is used in breadth-first search algorithms, while stack is used in depth-first search algorithms.
