Log Linear Voltage dB V to Volts Volts to dB V dBV to Volts Volts to dBV dBV to dB V dB V to dBV Term Conversion
V = 10((dBV 120) / 20)
dBV = 20 log (V ) + 120
dBm to dBuV dBuV to dBm dBuA to dBm dBm to dBuA dBuA to dBuV dBuV to dBuA
dBv = 90 + 10 log( Z ) + dBm dBm = dBV 90 10 log( Z )
V = 10(dBV / 20)
dBV = 20 log (V ) dBV = dBV + 120 dBV = dBV 120
dBm = dBA + 10 log( Z ) 90 dBA = dBm 10 log( Z ) + 90 dBV = dBA + 20 log( Z ) dBA = dBV 20 log( Z )
A= V Z W= V2 Z
Log Linear Power dBm to Watts Watts to dBm dBW to Watts Watts to dBW dBW to dBm dBm to dBW
Volts to Amps & Watts
W = 10((dBm 30) / 10)
dBm = 10 log(W ) + 30
Amps to Volts & Watts
V = A* Z
W = A2 * Z A= W Z
Watts to Volts & Amps
V = W *Z
W = 10(dBW / 10)
dBw = 10 log(W ) dBm = dBW + 30 dBW……
