We have seen that the b 2 - 4 ac portion of the quadratic formula, called the discriminant , can tell us the type of roots of a quadratic equation. The quadratic formula can also give us information about the relationship between the roots and the coefficient of the second term and the constant of the equation itself. Consider the following:.

How to find the product of sum and difference of two binomials with the same terms and opposite signs? Worked-out examples on the product of sum and difference of two binomials :. Thus, the product of sum and difference of two binomials is equal to the square of the first term minus the square of the second term. Didn't find what you were looking for?

## Sum Of Product (SOP) & Product Of Sum (POS)

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. To be clearer in the concept of SOP, we need to know how a minterm operates. So, the term SOP is also defined as the expression which is completely of minterms.

Table of Contents. Sum of Product is the abbreviated form of SOP. Sum of product form is a form of expression in Boolean algebra in which different product terms of inputs are being summed together. To understand better about SOP, we need to know about min term. Minterm means the term that is true for a minimum number of combination of inputs.

The different forms of canonical expression which includes the sum of products SOP and products of the sum POS , The canonical expression can be defined as a Boolean expression which has either min term otherwise max term. Similarly, the product of sums POS mainly includes the max term , types of product of sums , k-map and schematic design of POS. In this, the different product inputs are being added together. The min term can be defined as, when the minimum combinations of inputs are high then the output will be high. The truth table of the min term is shown below. In the above table, there are three inputs namely X, Y, Z and the combinations of these inputs are 8.

Boolean functions expressed as a sum of minterms or product of maxterms are said to be in canonical form. Standard Form — A Boolean variable can be expressed in either true form or complemented form. In standard form Boolean function will contain all the variables in either true form or complemented form while in canonical number of variables depends on the output of SOP or POS. A Boolean function can be expressed algebraically from a given truth table by forming a :. From the above table it is clear that minterm is expressed in product format and maxterm is expressed in sum format. It is sometimes convenient to express a Boolean function in its sum of minterm form.

## Digital Circuits - Canonical & Standard Forms

Boolean Algebra. A boolean expression consisting entirely either of minterm or maxterm is called canonical expression. A boolean expression consisting purely of Minterms product terms is said to be in canonical sum of products form. Example lets say, we have a boolean function F defined on two variables A and B.

We will get four Boolean product terms by combining two variables x and y with logical AND operation. These Boolean product terms are called as min terms or standard product terms. Similarly, we will get four Boolean sum terms by combining two variables x and y with logical OR operation.

#### Different Forms of Canonical Expression

Он уставился на карточку с личными данными, приколотыми к блузке стоявшей перед ним женщины. Глава Отделения криптографии АНБ была не просто женщиной, а очень привлекательной женщиной. - Да нет, - замялся.  - Я просто… - Сьюзан Флетчер.  - Женщина улыбнулась и протянула ему тонкую изящную руку. - Дэвид Беккер.  - Он пожал ее руку.

Доброй ночи, сэр. - Но… Послышался щелчок положенной на рычаг трубки. Беккер беззвучно выругался и повесил трубку.

Меган? - позвал он и постучал. Никто не ответил, и Беккер толкнул дверь.  - Здесь есть кто-нибудь? - Он вошел. Похоже, никого.

Преодолев отвращение, Беккер открыл дверь. Регистратура. Бедлам. Так он и .

Два человека…. И вот Халохот уже за спиной жертвы. Как танцор, повторяющий отточенные движения, он взял чуть вправо, положил руку на плечо человеку в пиджаке цвета хаки, прицелился и… выстрелил. Раздались два приглушенных хлопка. Беккер вначале как бы застыл, потом начал медленно оседать.

- Если не по поводу колонки, то зачем вы пришли. Хороший вопрос, подумал Беккер, рисуя в воображении горы Смоки-Маунтинс. - Просто неформальная дипломатическая любезность, - солгал .

Я понимаю, - сказал.  - Извините за беспокойство. Повернувшись, он направился через фойе к выходу, где находилось вишневое бюро, которое привлекло его внимание, когда он входил.
