๐ Poster Overview:
This comprehensive Sinhala ICT poster illustrates digital logic gates, truth tables, Boolean laws, and real-world circuit representations, ideal for GCE A/L and O/L students, ICT teachers, and exam preparation.
๐ข Sections & Topics Covered:
๐ถ 1. Digital Logic Gates (with Truth Tables)
- AND Gate (x = A ยท B)
- OR Gate (x = A + B)
- NOT Gate (x = Aโฒ)
- XOR Gate (Exclusive OR: x = AโB)
- NAND Gate (x = (AB)โฒ)
- NOR Gate (x = (A + B)โฒ)
- XNOR Gate (Exclusive NOR: x = AโฒBโฒ + AB)
๐ Sinhala explanations under each gate explain behavior in simple terms.
๐ 2. Boolean Laws (Purple Section)
Includes laws like:
- Annulment Law: Aยท0 = 0
- Identity Law: A + 0 = A
- Complement Law: A + Aโฒ = 1
- Idempotent Law: A + A = A
- De Morganโs Theorem:
- (A + B)โ = AโยทBโ
- (AยทB)โ = Aโ + Bโ
๐ Example simplification of:
(A + B)(A + C)
โ Simplified to A + BยทC, step-by-step using laws.
