Digital Circuits and Systems Logic Minimization

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

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).
