- What do these units of measurement mean?
In Analogue Electronic class, the Prof uses $20 \log_{10}$ and in my Networks and Protocols class, the Prof uses $10 \log_{10}$ but they both refer to $\text{decibel}$ (unless my hearing is impaired.)
- I would like to understand the connection of these two ($20 \log_{10}$ and $10 \log_{10}$) to $\text{bel}$ and $\text{decibel}$.
