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?
