T type attenuator design equations derived from first principles

The t type attenuator is a very useful circuit and is used quite extensively to not only attenuate signals but also to match inputs and outputs. This post presents the derivation of the design equations for this type of attenuator. The equations have been derived for a symmetric t type attenuator with equal I/O impedances.
