Date: January 17th, 2026 8:13 AM Author: ,.,..,.,..,.,.,.,..,.,.,,..,..,.,,..,.,,. this is an extremely good paper so far. i'm not ready to discuss the whole thing yet, but i'm into it a bit, and i should lay down some very preliminary ideas to begin to ground this whole thing for non-experts.
shannon's job here is to formalize the problem of communication. not some sort of habermas generality about psycho-emotive human communication, but the actual components of a 'message' in theory. what does it even mean to 'communicate' anything at all?
shannon's approach is to decompose 'message' into its barest constituent units, which he cites other theorists before himself as describing in terms of 'bits.' for example, when he talks about television transmissions, he describes them in terms of XY grid coordinates (the individual dots appearing on a screen) at any given moment, and then each coordinate has a motion in terms of time.
there is a unit of time in which each XY coordinate shifts value. in his era, it would have been the standard refresh rate in terms of hertz, which was the rate at which a cathode ray tube could scan a particular field. or around 30 frames per second.
in this type of 'message,' we now have a specific set of data (dots per image and image per unit of time) which must now be transmitted between a sender and a receiver. this data can be described in terms of bits to express the overall size of the transmission. easy enough, no?
NO!
because we have INTERFERENCE. interference is any sort of additional data contributed to the set of data which defines our original message. interference can come from any source (weather, hackers, animals chewing through wires, etc.). in terms of our analog TV example, interference visually represents as STATIC. static is the shit we don't want.
shannon's task from this point forward is to establish methods by which to deal with interference, and to reconstruct - as best he can - the original and purest form of the 'message' prior to its transmission.
to be continued, probably. |
