Digital Circuits and Systems Logic Minimization URL of NPTEL lecture hyper link: Reflection Spot Question: Why do we need to consider using less number of gates to design the same circuit? Reflection Spot Answer: Using less number of gates • Increases the speed of operation of the circuit • Decreases the cost • Less consumption of power • Saving in hardware Souce: WikipediaCircuit-minimization.svg

LbD:1 At 26.46 Can you compare the two methods to simplify the Logic expression discussing the advantages and disadvantages. Answer: The non confirmation of the minimized expression by Boolean algebra is not much advantageous than a systematic method(K-Maps) which gives the final minimized expression. minimization and comparing the expression obtained from the two methods will reveal that K-map method is most systematic method.

LbD At 12:32 For what we use minimization of logic expression is used? a. Design of Sequential Circuits b. Design of Combinational circuits c. Both d. None. Answer: All the combinational and sequential circuits are designed based on the simplified expression what was obtained after using any of the two methods(Boolean Algebra and K-Maps).
