WebThe damping factor, also called loss, is the extent to which a passive device reduces the strength of a signal. Amplification means voltage ratio V2 / V1 = Vout / Vin, and voltage gain in dB = 20 × log ( V2 / V1 ). Convert Decibels to Voltage Gain / Loss Convert Voltage Gain / Loss to Decibels • Voltage and Gain • WebThe ratio of the positive dB is the inverse of the negative dB, e.g. +10dB is a ratio of 10 times and -10 dB is a ratio of 1/10 or 0.1. Thus 10 dB is a ratio of 10 times: +10 dB means the power measured is 10 times greater than the reference power and … http://www.sengpielaudio.com/calculator-db.htm iplow
