Fun with Amplitude Modulation

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

• Digital audio player

• 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.

• Yes, but only in digital radios.

• No, amplitude modulation is not used in radios.

• Amplitude modulation is only used in television broadcasts.

What does AM stand for in amplitude modulation?

Can you hear music on an AM radio?

• No, AM radios cannot pick up any audio signals.

• No, AM radios only receive talk shows.

• Yes, you can hear music on an AM radio.

• Yes, but only classical music can be heard.

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?

• Radio waves

• Sound waves

• Seismic waves

• Light waves
