dc transmission is easy.but it costwies greater than the ac
transmission line.bcoz auxillary equipment need
(converter,inverter).
incase of ac transmission line economic than the dc t/m
line.but it complicate than the dc t/m line.becoz here
3wire or 4wire t/m line.
we are consider in now a days,the t/m line should be cost
effective.so we are used ac t/m line in now a days.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
