Question: PdB = 10 log10 pover p [P, Pref = power (watts)] If Pref =_001 watts, what is the power in dB when P = 2

PdB = 10 log10 pover p [P, Pref = power (watts)] If Pref =_001 watts, what is the power in dB when P = 2 watts? The output of an audio amplifier can be compared to its input using the following formula: AVdB = 20 log10 v over v [Vout, Vin = voltage (volts), AV = change in voltage] Show that AV is always equal to 12 dB if the output is four times the voltage of the input
