alternator is designed to rotate through an angle of
360degrees during operation one of the phase will be
reaching max and other will be in zero position so by this
the wave form will be pulsating and the first wave generated
will be ac in every machine so we cannot produce other
waveforms....to produce other wave forms u can go for invertors

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?
