3. What is the primary function of modulation in communication
systems?
o A) To amplify signals
o B) To convert information into a form suitable for
transmission
, o C) To filter noise
o D) To encrypt data
Answer: B
Rationale: Modulation is essential for converting
information (like audio or video) into a format suitable for
transmission over a communication medium.
4. Which modulation technique is commonly used in AM radio
broadcasting?
o A) Frequency Modulation (FM)
o B) Amplitude Modulation (AM)

o D) Quadrature Amplitude Modulation (QAM)
Answer: B
Rationale: Amplitude Modulation (AM) is the primary
technique used for broadcasting radio signals in the AM
band.
5. What does the term 'bandwidth' refer to in communication
systems?
o A) The range of frequencies available for transmission
o B) The strength of a signal
o C) The distance a signal can travel
o D) The cost of transmission
Answer: A
Rationale: Bandwidth refers to the range of frequencies that
can be used to transmit data, influencing the amount of data
transmitted in a given time.
