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.
digital and binary are used interchangeably. In the following sections we summarize some conventions for de ning the binary states and for doing binary arithmetic. 1.1 Binary Logic States The following table attempts to make correspondences between conventions for …
