R

Z = 600Ω

K = 15dB = 15

= 859.54 Ω

= 600 (30.6226 / 11.2468)

= 1633.67 Ω

Can someone please confirm if I am on the right lines? Thanks

## Homework Statement

Design a ∏ section symmetrical attenuator to provide a voltage attenuation of 15 dB and a characteristic impedance of 600 Ω.

## Homework Equations

Z

_{S}= Z_{L}= ZR

_{1}= R_{3}= Z (K + 1 / K -1)R

_{2}= Z (K^{2}- 1 / 2 K)## The Attempt at a Solution

Z = 600Ω

K = 15dB = 15

^{(15/20)}= 5.6234**R1 = R3 =**600 (5.6234 + 1 / 5.6234 - 1)= 859.54 Ω

**R2 =**600 (5.6234^{2}- 1 / 2 x 5.6234)= 600 (30.6226 / 11.2468)

= 1633.67 Ω

Can someone please confirm if I am on the right lines? Thanks
