Lecture Notes for Digital ElectronicsRaymond E. FreyPhysics DepartmentUniversity of OregonEugene, OR 97403, 20001 Basic Digital ConceptsBy converting continuous analog signals into a nite number of discrete states, a processcalleddigitization, then to the extent that the states are su ciently well separated so thatnoise does create errors, the resulting Digital signals allow the following (slightly idealized): storage over arbitrary periods of time flawless retrieval and reproduction of the stored information flawless transmission of the informationSome information is intrinsically Digital , so it is natural to process and manipulate itusing purely Digital techniques.
ible increase in the density of digital circuitry, its robust performance, its relatively low cost, and its speed. The requirement of using many bits in reproduction is no longer an issue: The more the better. This circuitry is based upon the transistor, which can be …
