Unit 1.2: Boolean Functions Synthesis 我们已经看到了两种Boolean function的表达方法——Boolean expression和Truth table,我们也知道了如何把Boolean expression化成truth table的形式,现在,我们要做的事与之刚好相反——从真值表到布尔表达式 方法: 举例来说,我们有上面这个真值表,要化为表达式的形式,首先就是每一行...
I am trying to solve these problems with truth tables using the formulas below. I am having a problem with the NOT to NAND I think i got the first 2 problems correct using: AND is equivalent to NOR, AND is equivalent to NAND The equations for AND, OR and NOT using the NAND operator...
(Sum of Products) formorPOS (Product of Sums) form. Sometimes, it can also be found in ahybrid of both forms. If the Boolean expression is inSOPform then NAND gates should be used for realization, on the contrary, if POS form is available we use NOR Gate for the realization of the ...
A logical statement that results in a Boolean value, either be True or False, is a Boolean expression. Sometimes, synonyms are used to express the statement such as ‘Yes’ for ‘True’ and ‘No’ for ‘False’. Also, 1 and 0 are used for digital circuits for True and False, respecti...
A law of Boolean algebra is an equation such as x∨(y∨z) = (x∨y)∨z between two Boolean terms, where a Boolean term is defined as an expression built up from variables and the constants 0 and 1 using the operations ∧, ∨, and ¬. The concept can be extended to terms involvi...

Thus, in either case, the overall expression is equal to the value of A alone. In the second case, this is even more obvious. If A is TRUE then the overall expression is TRUE, while if A is FALSE the second term is FALSE regardless of the value of B and the overall expression is...
EX - OR gate- This is the exclusive OR gate. It can be created by using a combination of the above-mentioned gates. R = A ⊕ B is the boolean expression. It means that R is true only if either A or B is true. EX - NOR gate- The boolean equation of the exclusive NOR gate is...

<programming> 2. (bool) The type of an expression with two possible values, "true" and "false". Also, a variable of Boolean type or a function with Boolean arguments or result. The most common Boolean functions areAND,ORandNOT.
