Construct and test the ∏ section symmetrical attenuator. Measure and record the Input & Output Voltages of the attenuator and determine the attenuation in dB.
Vout = Vin * [ R2 / (R1 + R2) ]
Decibel Attenuation (dB) = 20LOG10(Vout / vin)
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 Vin. Can someone please guide me to how to work out Vin?
