IQS-12004B

Transmission Portion of Notch

The attenuation data is divided into three regions:

³

transmission left (T

left

)

³

transmission right (T

right

)

³

notch

The transmission portion is the total range of T

left

and T

right

.

The wavelengths that segregate these regions are determined in a function
that will find the nominal attenuation for each of the left and right
shoulders. This is a statistical calculation and can be different for the right
and left shoulders.
