Design and Analysis of Wilkinson Power Divider Using ...
www.iosrjournals.orgThe Wilkinson power divider is a basically a three port network that is lossless when the output ports are matched, only reflected power is dissipated. Input power can be split into two or more in phase signals with the same amplitude. For a two way Wilkinson power divider using λ/4 impedance transformer having characteristic impedance 2Z0.

Monitor your use; hearing loss is a function of loudness versus time. The louder it is, the less time you can be exposed to it. The softer it is, the more time you can listen to it.

If 24 dBA is subtracted from 104 dBA, an employee wearing the protectors properly would be exposed to an approximate noise level of 80 dBA, which falls within acceptable limits.
