Broadcasting and Television Media Questions

Multiple choice
  1. Modem

  2. Satellite

  3. Fiber optic

  4. Coaxial cable

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A modem (modulator-demodulator) performs both modulation (converting digital signals to analog for transmission) and demodulation (converting received analog signals back to digital). This enables digital data to be transmitted over analog communication lines like telephone wires. Satellites, fiber optics, and coaxial cables are transmission media but don't perform modulation/demodulation.

Multiple choice
  1. Communication

  2. Noise

  3. Transfer

  4. Understanding

A Correct answer
Explanation

Communication is the correct answer because it fundamentally involves the exchange and sharing of information between a sender and receiver through various transmission media such as spoken words, written text, or digital signals. Noise interferes with communication, transfer is the movement itself, and understanding is the outcome, not the process of sharing.

  2. amplitude

  3. aloha

  4. attenuation

  5. amplitude modulation

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is the correct option. In ASK, the amplitude of the carrier signal is changed to create signal element. In ASK, one voltage level represents binary 1 and another voltage level represents binary 0. Thus, ASK that is implemented using only two levels is called binary amplitude shift keying (BASK).
