We are all more familiar with the terms SUM and PRODUCT in mathematics. Based on these terms, AND and OR logical operations are derived. Any kind of logical expression can be represented through these terms and there are many ways of expressing a logical function. AND represents the product relationship between the terms whereas OR represents sum relationship. So, Sum of Products and Product of Sums are the equivalent approaches of representing a logical expression. Through few principles, these … [Read more...]
Basic and All-inclusive concepts in Boolean Algebra
Initially, we are only with the propositions of true and false and these bivalent values introduced four laws of logic. But in many of the situations, there might be a need of more than these two values, in that case, the bivalent solution fits in. This bivalent approach is proposed by Aristotle. Making modifications to his approach George Boole founded Boolean Algebra which categorized multiple laws of relationship those are in between mathematical quantities constrained to one of two values: 1 … [Read more...]
What are Latches? and How they Differ from Flip-Flop?
In Digital Electronics, transmission and the storage of the data is the wide part of the computation. In both digital and informational technology sector data needs to be stored in the memory may be internal as in microcontroller or external as in micropocessors. To store the information in terms of bits the Latches and Flip-Flops are used. These are the basic storage elements that store binary values that are 0 and 1. Flip-Flop circuit is derived from the latch. Both elements belong to the … [Read more...]
Logic Gate: Working principle, Types, and Uses
In this digital world of electronics, the information is stored in the form of bits (Binary). Certain arithmetical operations like addition, subtraction, multiplication, and division are to be performed on these bits. The combination of 'Arithmetic Operation' with certain 'logic' using binary numbers was established by Leibniz. Further, the electrical circuits of switching based on vacuum tubes were designed. The invention of relays replaced the 'vacuum tubes' in switching circuits. Finally, … [Read more...]
What is a Combinational Logic Circuit : Types and Applications
As the scope of digital technology and digital electronic circuits extends to many domains such as software, healthcare, automation, business and many, electronic representations of Boolean functions, numerous bands of logic gates are utilized to represent these digital signals. In the digital logic scenario, the output is completely a function of the current input. In a consequence of this process, logic gates that are used to represent digital circuits are categorized as sequential logic … [Read more...]
