Question

Objectives:

Design T-pad and Pi-pad attenuators to provide a specified level of attenuation.

Model the design with Multisim and validate the specifications.

                                                                       

Design both T-pad and Pi-pad attenuators to provide an attenuation of 10 dB with impedance matching at both ends. The most common values are 50 Ω, 75 Ω, 125 Ω, 300 Ω, and 600 Ω. You will be assigned one of these values. Both the source and load resistances have that value. Use the internet and/or calculations to determine the three resistances (two values). Model the circuit and use Multisim DC Operating Point to validate the design. Complete the table below.
