Sequential Logic 
2016


“Sequential logic circuits have memory. Their outputs are a function of their state as well as their current inputs. The state of a sequential circuit is defined as the contents of all of the memory devices in the circuit.”

- “Sequential Logic Design.” 1996. UBC ECE. Web. 16 May 2016. <http://www.ece.ubc.ca/~edc/464/lectures/lec3.pdf>. 

Sequential logic in circuit theory is the idea that an output depends not only on the current input but on the history of past inputs (memory). Sequential Logic in this context is deployed to examine the ways in which we view a photograph or a series of photographs or a series of events for that matter. Each photograph is only in context when viewed with the previous photograph in mind; the viewer is relying on not only the current image they’re viewing but on their knowledge of the past images viewed. With each photograph acting as a memory device, we are able to interpret the circuit as a whole.
