When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In FM does the amplitude remains constant?
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.
When modulating freq is doubled then modulating index is halved and modulating voltage remains constant system is?
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
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
What is FM?
FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
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.
What remains constant in simple harmonic motion if friction is ignored?
In simple harmonic motion, the frequency remains constant if friction is ignored.
If the speed of a wave while the wavelength remains the same what happens to the frequency?
If the speed of a wave remains the same while the wavelength stays constant, the frequency also remains unchanged. This is because the relationship between the speed, wavelength, and frequency of a wave is given by the equation speed = frequency x wavelength. So, if two of these values are constant, the third one will be constant as well.
When sound enters another medium such as a wall what remains constant?
When sound enters another medium such as a wall, the frequency or pitch of the sound remains constant. The velocity or speed of sound may change depending on the properties of the medium, but the frequency remains the same.
What will happen as frequency of a wave increases and the speed remains constant?
As the frequency of a wave increases while the speed remains constant, the wavelength of the wave will decrease. This is because the speed of a wave is the product of its frequency and wavelength, according to the wave equation v = f * λ. So if the speed is constant and frequency increases, wavelength must decrease to maintain this relationship.
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
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.
