398 Attenuator Analysis In Figure P398, a two-port attenuator connects a 600- source to a 600- load.

3–98 Attenuator Analysis In Figure P3−98, a two-port attenuator connects a 600-Ω source to a 600-Ω load. Find the power delivered to the load in terms of vS. Remove the attenuator and find the power delivered to the load when the source is directly connected to the load. By what fraction does the attenuator reduce the power delivered to the 600-Ω load? Express the fraction in dB. Verify your results using Multisim.
