Carrier Swing & Deviation Ratio: Clarifying the Definitions

In summary, the conversation is about finding the definition of "carrier swing" and "deviation ratio." The speaker mentions that the definitions found online were vague and asks for help clarifying if it is related to frequency modulation synthesis. Another person provides a definition for "carrier swing" and a reference to a source with more information, asking for specific clarification on what the speaker is having trouble understanding.

Can anyone help me to find out the definition of "carrier swing"&"deviation ratio"?

The definitions which i found on surfing the net is too vague.Can someone help me with this?

Is it related to the following?
http://en.wikipedia.org/wiki/Frequency_modulation_synthesis

Edit: Found the following online:
Carrier Swing: The total deviation of a frequency-modulated or phase-modulated wave from the lowest instantaneous frequency to the highest instantaneous frequency.

Also found something here: www.ece.vill.edu/~mobasser/chapter3_FM.ppt [Broken] (Look on slide 14)

Does any of that help? What specifically were you having trouble understanding?

1. What is a carrier swing?

A carrier swing refers to the movement of a carrier wave, which is a continuous radio frequency signal used to transmit information. In telecommunications, carrier swing is used to measure the frequency deviation of a carrier wave from its original frequency.

2. What is deviation ratio?

Deviation ratio is a measure of the amount of frequency deviation in a signal compared to the original frequency of the carrier wave. It is expressed as a ratio, with the numerator representing the amount of deviation and the denominator representing the original frequency. A higher deviation ratio indicates a larger frequency deviation.

3. How is deviation ratio calculated?

Deviation ratio is calculated by dividing the amount of frequency deviation by the original frequency of the carrier wave. For example, if the original frequency is 100 MHz and the deviation is 10 kHz, the deviation ratio would be 10/100,000 or 0.0001.

4. Why is it important to clarify the definitions of carrier swing and deviation ratio?

Clarifying the definitions of carrier swing and deviation ratio is important because these terms are often used interchangeably, leading to confusion and misinterpretation. By clearly defining and understanding these concepts, scientists can accurately measure and analyze frequency deviations in carrier waves, which is crucial in fields such as telecommunications and signal processing.

5. How are carrier swing and deviation ratio used in research and experimentation?

Carrier swing and deviation ratio are important metrics in research and experimentation involving carrier waves. They are used to measure and analyze the accuracy and stability of carrier signals, as well as to detect and correct any deviations that may occur. These concepts are also used in the development and improvement of communication systems, such as radio and satellite communications.
