Webb22 maj 2016 · Another way is to use the formula : db = 20 * log (E 1 / E 0) . 20 = 20 * log (E 1 / 0.775) => E 1 = 7.75 V dBv and dBV As you might of guess dBV represents a ratio of voltages. The reference voltage is 1 volt RMS. You’re probably wondering if the lower case variant (dBv) is the same as the upper case (dBV). The answer is no.
