To express 0.32V in decibel millivolts (dBmV), we can use the following formula:

$\text{dBmV} = 20 \times \log_{10}\left(\frac{V}{1 \text{mV}}\right)$

Where:

• $V$ is the voltage in volts.
• 1 mV = 0.001 V.

Now, substitute 0.32V into the equation:

$\text{dBmV} = 20 \times \log_{10}\left(\frac{0.32}{0.001}\right)$

Let me calculate that.The voltage of 0.32V is equivalent to approximately 50.1 dBmV.

Tip: When working with decibels (dB), remember that a small change in dB can represent a large change in actual voltage or power due to the logarithmic nature of the scale.
