Tee Attenuator Circuit

A T-pad attenuator is an unbalanced attenuator network consisting of three non-inductive resistive elements connected together to form a "T" configuration, (hence its name). The formation of the resistive elements into a letter "T" shape means that the T-pad attenuator has the same value of resistance looking from either end. This formation then makes the "T-pad attenuator" a perfectly symmetrical attenuator.
