If you have a good understanding of the logic gate rules, it is possible to work out a simpler solution just by examining the truth table and thinking hard. Obviously, this circuit is much simpler than the original, having only two logic gates instead of five. Full PDF Package Download Full PDF Package. Answer (1 of 3): It is that circuit that performs operations depending upon the given input and initially feed conditions. Answer: The function given in this form identifies the “value” of the input that are true, if we consider them as a 4-digit binary number. Logic Circuit Simplification MCQs : This section focuses on the "Logic Circuit Simplification". Part 1. The two circuits, in this case, are equivalent to each other. LAB 2-Basic Logic Gates and Circuit Simplification OBJECTIVES: The objective of this lab is to become familiar with digital design in order to derive Boolean expressions that represent logic circuits and then simplifying these expressions using the rules of Boolean Algebra. So in order to simply and circuit there are mainly two methods:- 1. Write the Boolean expression for Y (the output of the circuit in Figure 1). If we translate a logic circuit’s function into symbolic (Boolean) form, and apply certain algebraic rules to the resulting equation to reduce the number of terms and/or arithmetic operations, the simplified equation may be translated back into circuit form for a logic circuit performing the same … Fill in the predicted output values in … Simplification of Combinational Logic Circuits Using Boolean Algebra Complex combinational logic circuits must be reduced without changing the function of the circuit. Nov 25, 2015. Logic gates can be strung together in many different ways. As you know, a logic expression represents a logic circuit with a certain number of gates. Y = Y = 2.
