Please verify my approach for calculation the minimal POS form for a function f.
STEPS:
- Find out the f' in sum of minterms.
- Minimize f' and find out minimal SOP form.
- Using DeMorgan's law, find out f. The calcuated f will be minimal and in SOP form.
Till now, I have been able to solve questions using this approach. However, I need a confirmation whether this method is actually correct and is bound to give me correct results all the time..!
