2. Design and Analyze Combinational Logic Circuits
Combinational logic circuits are defined by their outputs, which are determined solely by the current input values. Key components of such circuits include various types of logic gates and the principles of Boolean algebra to simplify and manipulate logic expressions. Designing these circuits involves several steps from understanding the problem to implementing the final circuit using various platforms.
