Re: HUM Modulation

I troubleshoot hum just like I do with carrier to noise, composite triple beat, second order beats, in channel and all the other issues........Divide and Conquer .......

> I have experience with troubleshooting several instances of hum in drop passives. (Neutral fault currents due to difference in power ground/cable ground/ and/or cable ground to ground rod. (Fix - splitter with block capacitors or AC block on input to splitter.)

> What about hum inside the HFC plant? I've never run across it, but was told it can happen from too much current on line splitters/ dcs, taps?. IS THIS something that you find on newer HFC passives? or mainly old plant? Also, I've been told it can come from power supplies, how do you find and fix this in the HFC portion should it become a problem?
