Digital Logic - Boolean Algebra
2. The number of canonical expressions that can be developed over a 3-valued boolean algebra is
- Option : D
- Explanation : Canonical form=SOP or POS No of min/MAX terms=23=8. Therefore, Canonical form will have 28 have terms. Zero term canonical forms=8C0=1. One term canonical forms=8C1=8. Two term canonical forms=8C2=28 Similarly total number of canonical expressions= 8C0+8C1+8C2+8C3+8C4+8C5+8C6+8C7+8C8=256
