in accordance with the design-formulas there gi\en, this network 

 possesses the following two-fold propcrt\- with reference to the a-section 

 characteristic reactance of the loaded line: When <r has any fixed 

 value between and 1 2, the network exactly simulates the <r-section 

 reactance, and exactly neutralizes the (1 - (t) -section reactance; or, 

 what is equivalent, when a has any fixed value between 1/2 and 1, 

 the network exactly neutralizes the a-section reactance and exactly 

 simulates the (1 — it) -sect ion reactance.
