  • Until recently the applications of modern algebra were mainly confined to other branches of mathematics. However, the importance of modern algebra and dis- crete structures to many areas of science and technology is now growing rapidly. It is being used extensively in computing science, physics, chemistry, and data communication as well as in new areas of mathematics such as combinatorics. We believe that the fundamentals of these applications can now be taught at the junior level.

  • Under the name of ideal circuit network, it is easy to make us understand that digital circuits are independent of the inner status and their outputs just only depend on the inputs. They are time constants and therefore Boolean algebra is a special suitable means of describing. In fact propagation delay time of circuit system should be in thought firstly in designing circuit network. In that case Boolean algebra does not seems to be fully suitable for describing actual circuit systems.

  • The textbook used by my predecessors assumed the reader had had some experience with electronics. The author went so far as to use screen captures from oscilloscopes and other test equipment to describe circuit properties. I soon found that this was a bad assumption to make when it came to students of computer science.

  • All digital systems are founded on logic design. Logic design transforms algorithms and processes conceived by people into computing machines. A grasp of digital logic is crucial to the understanding of other basic elements of digital systems, including microprocessors. This chapter addresses vital topics ranging from Boolean algebra to synchronous logic to timing analysis with the goal of providing a working set of knowledge that is the prerequisite for learning how to design and implement an unbounded range of digital systems....

  • There are many methods to design digital circuits without hazard, such as the use of Boolean algebra, algebra hazard, karnaugh map, matrix method, VHDL, etc. However, these methods are not very suitable for the design of circuit system such as design of GALS circuits. In this case, synchronization is the most optimal method. 1. Introduction Hazard is the essence of digital circuits including synchronous circuit and asynchronous circuit. Hazard occurs as much as “autumn’s leaves” [1] and has adverse impact on the working of digital circuits. ...

  • The inverse of a function, denoted by F', can be easily obtained from the truth table for F by simply changing all the 0’s to 1’s and 1’s to 0’s as shown in the truth table in Figure 7 under the column labeled F'. Thus, we can write the Boolean function for F' in the sum-of-products format, where the AND terms are obtained from those rows where F' = 1. Thus, we get F' = x'y'z' + x'y'z + x'yz' + xy'z' To deduce F' algebraically from F requires the use of DeMorgan’s theorem (Theorem 15a) twice. For example, using the same...
