I want to know about the circuit of a digital coomunication reciever. I want to know how clock can be extarcted from the recieved data if the coded signal is of the form NRZ-level ( that means 0 represented by 0 volts and 1 is represented by 5volts ).
Also I want to know how the extacted clock can be used to sample the recieved data to extract the message signal?
