 negative quantity, since we may always interchange Zi and 4Z2. 

 The consequences of this and of other elementary properties of this 

 artificial line are brought together in the following table:

The cycle of bands: stop ( + ), pass, stop ( — ), adopted for the 

 table, carries the attenuation factor e~^ around the periphery of
