In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
What else can I help you with?
What happens to the speed of a wave if the amplitude is doubled and the frequency holds constant?
If the amplitude of a wave is doubled while the frequency remains constant, the speed of the wave will not change. The speed of a wave is determined by the medium through which it is traveling, not by its amplitude or frequency.
On AM broadcasts what remains constant?
On AM broadcasts, the amplitude of the carrier wave remains constant. This means that the strength or power of the signal does not change, only the frequency of the signal is modulated to carry the audio information.
When the amplitude decreases what happens to the frequency?
When the amplitude decreases, the frequency remains constant. Amplitude and frequency are independent of each other in a wave. The frequency determines the pitch of the sound or the color of light, while the amplitude determines the intensity or loudness of the sound or brightness of light.
Does the frequency change when you increase the amplitude of a wave?
No, increasing the amplitude of a wave does not change its frequency. Frequency is determined by the number of complete oscillations or cycles of the wave that occur in a given time period, and this remains constant regardless of the wave's amplitude.
What happens to a wavelength when the amplitude and frequency are both increased?
When the amplitude and frequency of a wave are both increased, the wavelength remains constant. Amplitude affects the intensity or loudness of the wave, while frequency determines the pitch. Therefore, changing the amplitude and frequency does not alter the wavelength of the wave.
What does AM and FM mean?
am is amplitude modulation, fm, frequency modulation
Multiple choice question answer of AM modulation?
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
FM is better than AM?
FM is frequency modulation. The amplitude is held constant and the carrier frequency is varied. AM is amplitude modulation. The amplitude is varied and the carrier frequency is held constant.
Does frequency depend on amplitude for harmonic oscillators?
No, the frequency of a harmonic oscillator does not depend on its amplitude. The frequency is determined by the properties of the system, such as mass and spring constant, and remains constant regardless of the amplitude of the oscillation.
What happens to the speed of a wave if the amplitude is doubled and the frequency holds constant?
If the amplitude of a wave is doubled while the frequency remains constant, the speed of the wave will not change. The speed of a wave is determined by the medium through which it is traveling, not by its amplitude or frequency.
What are FM and AM?
Amplitude Modulation (AM) Frequency Modulation (FM)
What does am and fm?
fm- frequency modulated am- amplitude modulated
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Why is a limiter used in FM?
limiter mainly used to limit the amplitude of FM waveform.because of, in FM the frequency only varied but amplitude also varied due to noise . to cancel the amplitude variation limiter mainly used
What do the initials AM and FM relate to?
AM = Amplitude Modulation. FM = Frequency Modulation
What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
On AM broadcasts what remains constant?
On AM broadcasts, the amplitude of the carrier wave remains constant. This means that the strength or power of the signal does not change, only the frequency of the signal is modulated to carry the audio information.
