What is the signal voltage on cable?


I don't know about all CATV systems, but the one I did some design
work on was based on +10 dBmv at the street to all for up to four sets
per drop. +10 dBmv = 3.1623 mV.


Interesting.
I would think there would always be a lot more 60Hz noise than that.
High pass filter?
