What is amplitude modulation?
Amplitude modulation is a method of varying the amplitude of a carrier wave to encode information.
A process that involves changing the phase of a carrier wave to transmit data.
A technique used to increase the bandwidth of a signal without changing its amplitude.
A method of varying the frequency of a carrier wave to encode information.
Can you name a device that uses amplitude modulation?
AM radio transmitter
Satellite phone

FM radio transmitter
What happens to the sound when we change the amplitude?
Changing the amplitude has no effect on the sound.
Changing the amplitude affects the loudness of the sound.
Changing the amplitude only affects the duration of the sound.
Changing the amplitude affects the pitch of the sound.
Is amplitude modulation used in radios?
Yes, amplitude modulation is used in radios.

What is the main purpose of amplitude modulation?
To reduce interference in communication systems.
To enhance sound quality in audio recordings.
To increase the power of radio signals.
To encode information for transmission over radio waves.
Does amplitude modulation change the frequency of a signal?
Amplitude modulation alters the frequency while keeping the amplitude constant.
Amplitude modulation can increase the frequency of a signal.
No, amplitude modulation does not change the frequency of the original signal.
Yes, amplitude modulation changes the frequency of the original signal.
What type of waves does amplitude modulation use?
