Following on from above post, this is why ISDN has vastly superior pings to standard 56k modems. There is no modulation/demodulation involved it's a pure digital connection. The only reason the pings on ISDN in some cases are well above those on ADSL is that the ISDN tends to travel along the voice network, which is not nearly as fine tuned for latency as the data one.
Cable modems tend to be faster than ADSL as ntl's backbone network is more decentralised than BT's and data tends to take a shorter physical path through higher specification routers etc to reach its' destination.
Electrical resistance affects the strength of a signal, not how fast it travels.
