measuring telephone line impedance
how can i measure long distance cooper Line impedance ?
i will measure the empedance of a telephone line which is cooper (0.9mm) and it is long distance 1km ~ 6 km .
there will be no any telephone signals, the 2 wires are reserved for this meauserement.
i want to use ADC and MCU pic16f876.
also, it will not be very sensitive , for example 30 ohm ~50 ohm and multiples.
**broken link removed**
not: of course not with Mulitmeter or ohmmeter
