dB to everything
dB dBm dBV to ratio, power, voltage, VSWR
constants:c
Parameters
dB | dBm | dBV | Return Loss
\(dB\)
Output
Percent p
`Delta d=10log_{10}(1+p%)`
Power P
`Power(dBm)=10 log_{10} (P/(1mW))`
Voltage V
`V(dBV)=20log_{10}(V_{rms}/{1V})`
Reflection Coefficient `Gamma`
`RL=-20log_{10} Gamma`
VSWR
`VSWR=(1+Gamma)/(1-Gamma)`
