could someone HELP me answer this questions PLEASE.... :-\
a) can i send a digital signal through the coax cable (RF) used by CATV providers?
b) is it really true that a digital signal can ride on an analog signal? how? or is there a circuit that can do this?
c) is it possible or is there a way that a multiplexed analog signal can be converted into a digital signal?
d) and lastly, is it possible that a modulated analog signal can be modulated again with a different type of modulation?
thank you and good day!
