The field strength corresponds to uv, that is, the voltage amplitude, such as
-20db corresponds to 22.387mv
For example, if we say there is -20db attenuation, that is to say, after the input signal passes through the circuit, the output amplitude is reduced by 22.387mv.
For example, if the input is 100mv and the output is measured to be 77.613mv after a series of circuits, then we say that the circuit attenuation is -20db.
For example, if there is a gain of 20db, that is to say, after the input signal passes through the circuit, the output amplitude increases by 22.387mv.
For example, if the input is 100mv and the output is measured to be 122.387mv after a series of circuits, then we say the circuit gain is 20dm.
