While appearing in the GATE ECE exam, Minimization MCQ questions constitute an important part of the paper. As they test the candidate on the parameters of critical thinking and problem solving, these skills also come in handy while appearing in other exams that are designed to evaluate the understanding of STEM concepts of an applicant, such as NIELIT, SSC JE, and the kind.
Minimization in digital logic and boolean algebra refers to the process of simplifying and breaking down complex algebraic expressions into their most rudimentary terms. It plays an important role in the analysis of logical circuits, for it serves to reduce complex combination logical circuits without interrupting the basic function of the circuit. Consequently, a firm grasp over minimization becomes a prerequisite for anyone wishing to appear on the GATE ECE paper.
Given below are the minimization topics for GATE ECE that a candidate is expected to cover while covering the minimization GATE syllabus and while taking minimization quiz.
It is a field of engineering in which the representation of all the different constituent sequences and signals of a digital circuit is achieved with numbers. Mostly finding usage in electronic devices, the importance of digital logic makes minimization for computer science an important field of study. Broadly, there are two kinds of digital logic circuits- combinational and sequential.
In the field of mathematics and logic, a boolean function refers to a function of which the arguments and the function itself derive their values from a set comprising two values. For this reason, boolean functions are also termed as switching functions. If in a boolean function, the number of variables or entries is n, then the number of all possible combinations of the variables will always amount to be 2n.
Sum of Products (SOP)
Sum of Products refers to a type of Boolean algebra expression that consists of the addition of the different product inputs. The products of these inputs in Boolean logical AND while the addition is Boolean logical OR.
Product of Sums (POS)
Product of Sums refers to a type of Boolean algebra expression which consists of sums comprising single or multiple variables that might be present either in their true normal form or in their complemented form or even as combinations of both.
The Karnaugh map is a graphical method and technique of solving logical expressions and simplifying Boolean expressions. K-maps use truth tables to provide us with a more straightforward form of a complicated logical expression.
Listed below are a set of tips and tricks that can prove extremely beneficial for students while solving minimization for computer science and ECE in GATE and other technical examinations.
The following points shed light on the importance of minimization in the GATE and other similar entrance examinations.
