What does AM stand for in radio broadcasting?

• Audio Modulation

• Amplitude Modulation

• Amplitude Measurement

• Analog Modulation

How does FM differ from AM in terms of modulation?

• FM varies the amplitude of the carrier wave, while AM varies the frequency.

• FM uses a constant frequency, while AM uses a variable frequency.

• FM differs from AM in that FM varies the frequency of the carrier wave, while AM varies the amplitude of the carrier wave.

• FM and AM both vary the amplitude of the carrier wave.

What is the primary advantage of FM over AM?

• FM is less complex to implement than AM.

• FM uses less bandwidth than AM.

• FM has a longer range than AM.

• FM has better noise resistance than AM.

Define PM in the context of signal modulation.

• Phase Modulation (PM)

• Pulse Modulation (PM)

• Phase Measurement (PM)

• Power Modulation (PM)

Which type of modulation is more susceptible to noise: AM, FM, or PM?

• AM

• AM-FM

• AM-PM

• PM

What is the frequency range typically used for AM broadcasting?

• 400 kHz to 800 kHz

• 2000 kHz to 3000 kHz

• 100 kHz to 300 kHz

• 530 kHz to 1700 kHz

Explain how the amplitude of a signal is used in AM.

• The amplitude in AM is constant and does not vary with the input signal.

• The amplitude of a signal in AM is used to encode the information by varying the strength of the carrier wave according to the input signal.

• Amplitude modulation does not involve the carrier wave's strength.

• The amplitude is used to determine the frequency of the signal.

In FM, what aspect of the carrier wave is varied?

• The frequency of the carrier wave is varied.

• The wavelength of the carrier wave is varied.

• The phase of the carrier wave is varied.

• The amplitude of the carrier wave is varied.

What is one common application of PM?

• Construction project management

• Software development management

• Event planning coordination

• Marketing campaign oversight

How does the bandwidth of FM compare to that of AM?

• FM has a smaller bandwidth than AM.

• FM has a larger bandwidth than AM.

• FM and AM have the same bandwidth.

• AM has a larger bandwidth than FM.
