The average of maximum and minimum values of the attenuation over the specified frequency range for a given attenuation value in dB.
Modulation
When, with all other ports set to isolation, one port is repeatedly switched ON and OFF.
Monotonicity
The increase of attenuation level as the control input level increases. At no point does an increase in control input state cause a decrease in attenuation at any frequency or attenuation level.
