Q:

Which of the following is true about carrier signal?

A) Carrier signals have low frequency B) Carrier signals are used to increase the wavelength of the signal
C) Carrier signals have high frequency D) Carrier signals and message signals are the same
 
Answer & Explanation Answer: C) Carrier signals have high frequency

Explanation: Carrier signals have high frequencies and hence are used in the transmission of radio waves. This is because since space is an insulator, for having electric current in order to magnetize it is only possible if the source contains a rate of change of voltage or a varying electric field. All the other statements are not valid.

Q:

Which one of the following is a way to produce a signal?

A) Superimposition with a carrier signal B) Superimposition with a received signal
C) Superimposition with a transmitted signal D) No superimposition is required
 
Answer & Explanation Answer: A) Superimposition with a carrier signal

Explanation: Any signal that is generated from a source and is required to be sent over large distances from the source to the receiver, needs to be modified. This can be achieved by superimposition with a carrier signal in order to ensure that the signal is transmitted in a suitable bandwidth.

Q:

Identify the type of modulation where the modulating wave is superimposed on a high-frequency carrier wave.

A) Phase modulation B) Amplitude modulation
C) Frequency modulation D) Wavelength modulation
 
Answer & Explanation Answer: B) Amplitude modulation

Explanation: In Amplitude modulation, the modulating wave is superimposed on a high-frequency carrier wave such that the amplitude of the modulated wave varies as the amplitude of the modulating wave. The frequency of the modulated wave is equal to the frequency of the carrier wave.

Q:

How can the noise be reduced in AM signal?

A) Increasing amplitude B) Increasing wavelength
C) Increasing bandwidth D) Increasing frequency deviation
 
Answer & Explanation Answer: D) Increasing frequency deviation

Explanation: Noise is a form of amplitude variations in the transmitted signal due to several factors such as the atmosphere, industries, etc. This noise can be reduced by increasing the deviation of the frequency of the signal.
