What else can I help you with?
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?
modulation
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
When modulation frequency is doubled modulation index also doubled in case of FM or pm or am?
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
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
An electric current that is varied to represent information is what?
An electric current that is varied to represent information is called a modulated current. This modulation can take various forms, such as amplitude modulation (AM), frequency modulation (FM), or pulse modulation, and is commonly used in telecommunications to transmit data over long distances efficiently.
Where does a modulation from the home key to the new key in the exposition of the sonata form take place?
In the exposition of the sonata form, the modulation from the home key to the new key typically occurs at the transition or bridge section, which follows the first theme. This transition prepares for the introduction of the second theme, which is usually presented in a contrasting key, often the dominant key in major works. This modulation is crucial for establishing the tonal framework for the development section that follows.
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
