Decibel Calculator

Berikut merupakan tools untuk Anda yang profesional dalam menentukan dB impedensi dan gain.


dB= 20log(V1/V2)= 10log(P1/P2)

Decibels (dB) Voltage Gain Power Gain

The dBm is a logarithmic measure of power compared to 1mW. It can be converted to a voltage, if the load is known. Typically the load is 50 ohms.


dBm= 10log(p1/.001)

dBm Power(Watts) Voltage DC Vp of Sinusoid
