The formula to calculate dBm from uV is:
\[ \text{dBm} = 20 \log_{10} (\text{uV}) - 10 \log_{10} (\text{Z}) - 90 \]
Where:
dBm, sometimes referred to as dBmw, is a unit of measure that describes the ratio of power in relation to one watt. It is commonly used in telecommunications and radio frequency applications to express power levels.
Let's assume the following values:
Using the formula:
\[ \text{dBm} = 20 \log_{10} (1000) - 10 \log_{10} (50) - 90 = -46.99 \]
The dBm value is -46.99.
Let's assume the following values:
Using the formula:
\[ \text{dBm} = 20 \log_{10} (2000) - 10 \log_{10} (75) - 90 = -42.73 \]
The dBm value is -42.73.
