When we use the term dB to indicate a voltage amplification factor (gain), no reference is implied. 101 dB of
Voltage Amplification means that if you take 20 time the Log (base 10) of the output voltage divided by the input
voltage, the answer will be 101 dB
When we use the term dBu to indicate a voltage level, we are implying a 0.775 volt reference voltage level. Thus, a
voltage level expressed as +4 dB was calculated by taking 20 times the log (base 10) of the actual voltage (1.23
volts) divided by the reference voltage (0.775 volts)
The choice of a 0.775 volt reference was not arbitrary. dBm is a common method of rating power levels (as
opposed to our voltage level ratings). The 0 dBm reference is one milliwatt (1/1000th watt). If an output device pro-
duces 0 dBm into exactly 600 ohms, the voltage level is 0.775 volts. Thus, for true 600 ohm lines, the dBm power
terminology and our dBu voltage terminology are equivalent.
