Title: Feature: Amplitude (voltage) ratio

- [Amplitude ratio](http://en.wikipedia.org/wiki/Decibel#Voltage) is the strength of a signal expressed in decibels (dB) relative to one volt RMS.
- Amplitude ratios are commonly used in audio, RF, and telecommunications engineering.
- Added conversions between voltage and power ratios.
