Basic Combinational Logic Design
- A combinational circuit is a digital circuit whose output is purely a function of its current inputs.
- It has no memory(past inputs).
- A simple technique is used to design a combinational circuit using basic logic gates.
- Step1:- Problem description(output in terms of inputs).
- Step2:- Translation of description into truth table with all possible input configurations.
- Step3:- Derivation of output equations from output columns.
- Step4:- Minimization of output equations by using k-maps to minimize the number of logic gates.
- Step5:- Obtaining the final circuit from the output equations.
