Function Documentation

I2dB()

template<typename T>

T lass::num::I2dB

(

const T &

iValue

)

Converts an intensity into decibels.

The intensity represents the intensity in all directions expressed in Watts/m^2, referenced to 10^-12.

(

const T &

iValue

)

Converts decibels into an intensity.

The intensity represents the intensity in all directions expressed in Watts/m^2, referenced to 10^-12
