Another embarrassing confession – what is the difference? Oh, I get the 1’s and 0’s coding thing….but…I need a better grasp of the big picture.
“Success in digital processors and memory chips boils down to recognizing accurately and rapidly whether a circuit is on or off. That simplicity makes measuring performance and cost relatively straightforward and has even allowed the industry to predict fairly accurately how fast digital technology will improve. But the more variable world of analog data defies the emergence of a blockbuster analog design that fits many products.” From: A digital world with analog as it’s workhorse”.
It seems that analog technology has to do with sound? “Analog refers to electronic transmission accomplished by adding signals of varying frequency or amplitude to carrier waves of a given frequency of alternating electromagnetic current.” I’m picking up on the frequency part of this definition, but actually it’s talking about electricity.
Frequency is “the number of occurrences within a given time period (usually 1 second).
Electricity is “physical phenomenon associated with stationary or moving electrons and protons.”
Electrons and protons….so maybe what I need next to understand is the relationship between electricity and quantum mechanics? (I’m also confused by the apparent conflation of quantum mechanics and quantum physics – are they technically different?)
