Is the signal within a LAN all digital
Posted on 2011-05-11
I have a discucssion with my friend about digital or analog signal. I know that from a modem will translate (or modulate) the digital signal from the computer or router to an analog signal and send to the network. Does it means that all the signal within a simple home LAN is digital ? I can transfer almost 0.5 GBit/s with my LANs. What is the signal format in that cat6 cable. Is it really digital ? Or the digital signal is actually embedded inside some analog signal ?
