## Homework Statement

Construct and test the ∏ section symmetrical attenuator. Measure and record the Input & Output Voltages of the attenuator and determine the attenuation in dB.

## Homework Equations

V

_{out}= V

_{in}* [ R

_{2}/ (R

_{1}+ R

_{2}) ]

Decibel Attenuation (dB) = 20LOG

_{10}(V

_{out}/ v

_{in})

## The Attempt at a Solution

I have included an attachment for this question. The main area where I am confused at the moment is the number for V

_{in}. Can someone please guide me to how to work out V

_{in}?
