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.
The most signi cant bit (MSB) is the bit representing the highest power of 2, and the LSB represents the lowest power of 2. Arithmetic with unsigned binary is analogous to decimal. For example 1-bit addition and multiplication are as follows: 0+0 = 0, 0+1 = …
