Bits is a universal currency to transmit information. As long as we can encode

Source-Channel Separation Theorem

“Are we loosing information by using Bits? No.”


If a source can be transmitted over a channel at a certain resolution, then it can be transmitted using a binary interface between the source and channel at the same resolution.


If a communication channel has a certain fidelity for arbitrary data, encoding the data by bits will not change the fidelity of the channel.
