3.2 Sum of Products & Product of Sums Any Boolean expression can be simplified in many different ways resulting in different forms of the same Boolean function. 2.3.1 Derive the POS standard form (expression) of the function f(D,C,B,A) applying the algebraic manipulation method to its SOP form given by equation (A.2-1). Simplification of Boolean Expression, Standard POS form, Minterms and Maxterms KARNAUGH MAP, Mapping a non-standard SOP Expression Converting between POS and SOP using the K-map 3. NC SOP Ver 1.15v2 Chpt 2 POS CAD Kiosk .docx 2-2 10-Oct-17 2.1 Background This chapter of the SOP describes the operation of the Navy Cash Point- Of-Sale device (POS), Card Accepting Device (CAD), and Kiosk. Implementation of 4x1 multiplexer using logic gates. they can be converted into one another. Hint#3: Apply repeatedly the postulate

2.1.1 Applications . Canonical POS and canonical SOP are inter-convertible i.e. The Karnaugh Map Provides a method for simplifying Boolean expressions It will produce the simplest SOP and POS expressions Works best for less than 6 variables Similar to a truth table => it maps all possibilities A Karnaugh map is an array of cells arranged in a special manner The number of cells is 2n where n = number of variables A 3-Variable Karnaugh Map: The Ultimate Guide To Creating Restaurant Standard Operating Procedures (Restaurant SOP) A restaurant business requires a preset list of rules and norms to work efficiently. For SOP put 1’s in blocks of K-map respective to the minterms (0’s elsewhere). 5. There are three applications loaded on each of the devices, the Navy Cash Shell, Navy Cash Verification of state tables of RS, JK, T and D flip-flops using NAND & NOR gates. Implementation and verification of Decoder/De-multiplexer and Encoder using logic gates. 2.3 POS FORM OF LOGIC FUNCTIONS .

All Boolean expressions, regardless of their forms, can be converted into one of two standard forms; the … Logic Gates and Boolean Algebra •Logic Gates –Inverter, OR, AND, Buffer, NOR, NAND, XOR, XNOR •Boolean Theorem –Commutative, Associative, Distributive Laws –Basic Rules •DeMorgan’s Theorem •Universal Gates –NAND and NOR •Canonical/Standard Forms of Logic –Sum of Product (SOP) –Product of Sum (POS) –Minterm and Maxterm Implementation of 4-bit … Make rectangular groups containing total terms in power of two like 2,4,8 ..(except 1) and try to cover as many elements as you can in one group. 4 KARNAUGH MAP MINIMIZATION A Karnaugh map provides a systematic method for simplifying Boolean expressions and, if properly used, will produce the simplest SOP or POS expression possible, known as the minimum expression. As you have seen, the effectiveness of algebraic simplification depends on your familiarity with all the SOP and POS forms. Conversion From Canonical POS to SOP The product of Sum expression can be converted into Sum of Product form only if the expression is in canonical form. SOP Number: Kitchen / F&B Production SOP – 34 Department: All Kitchen and Stewarding Staff Date Issued: 17-Feb-2019 Time to Train: 30 Minutes Purpose of this SOP: Establish standard policies for the proper procedure for washing and sanitizing kitchen equipment, kitchen utensils and F&B service equipment to reduce microbiological contamination and chemical contamination to … 4. Show the derivation process and show the POS form of the function f(D,C,B,A) as the equation (2.3-1). 6. For POS put 0’s in blocks of K-map respective to the maxterms(1’s elsewhere).
