The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Amplitude Modulation

Asked by Rafi-muqaddar in Math & Science

Tags: modulation, amplitude, power

hi
I wonder if anybody could help me. I have got one question with 4 parts

Q A 400Khz sine wave, having a peak amplitude of 7V, is amplitude modulated by a 25Khz sine wave that has a peak amplitude of 2.5V

calculate
1. The depth of modulation
2. The frequencies in the modulated signal
3. The power in each frequency componenet if modulated signal is applied to a 2K resistor
4. Above mentioned AM signal has been converted to an single side band signal, now by reducing the carrier by 30dB and eliminating oneof the sidebands and assigning all of the saved power to remaining sideband. By how much would the power in this remanining sideband have increased

please provide me with the formulas as well for my understanding
Thanks
