What is Half Subtractor : Working and Its Applications, K-MAP, Circuit using NAND Gate
To process the information like light or sound from one point to other we can use analog circuits by giving proper inputs in the form of analog signals. In this process, there are chances of noise being picked up by the input analog signals and this may lead to loss in the output signal, it means whatever the input we are processing at the input level is not equal to the output stage. To, overcome these digital circuits are implemented. Digital circuit can be designed with logic gates. Logic … [Read more...]
Sum of Products and Product of Sums : Types and Schematic Diagrams
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...]
