In some transmission frame structures, there are some bits for "dc line balancing". What are those used for?:confused:
That's a new term to me. I guess it's a fettle so that the average DC level of the transmitted signal is zero. Nulling DC has been an issue since the first days of telegraphy, and a lot of coding systems (NRZ, EFM, Manchester etc.) are designed to have zero DC component.
