Question 6

Decibels referenced to 0.775 volt are called __________.

Accepted Answer

Decibels referenced to 0.775 volts are commonly used in audio engineering, and they are referred to as dBu. dBu stands for "decibels unloaded," which means that the signal being measured is not connected to any load or impedances. This is a common reference level in audio circuits and systems, as it corresponds to a voltage level of 0 dBm (decibels referenced to 1 milliwatt), which is a standard reference for measuring power levels in audio systems. dBV, on the other hand, refers to decibels referenced to 1 volt, while dBm is referenced to 1 milliwatt. Therefore, A) is the best choice: dBu.
