Assume that you are required to determine the attenuation of a transmission line. If the input is 60 milliwatts and
the output power is 12 milliwatts, the attenuation is:
A transmission line requiring minimum attenuation is being installed between stations A and B. The type of
transmission line that has the lowest attenuation for a given distance is:
Assume that the distortion of a voice-frequency signal in a transmission line is due to the unequal attenuation of
the different frequencies. This distortion, as well as the attenuation, in the line can be reduced by the addition of:
Inductive coupling (fig. 63) between the conductors of a transmission line may cause crosstalk between adjacent
circuits. One method used to reduce this crosstalk is to:
install filters in the lines.
install repeating coils in the lines.
transpose the conductors of the lines.
