🎓 Digital Logic Gates & Boolean Algebra – Sinhala Educational Poster

📁 Editable PNG File – Size: 7000×3000

📘 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.

🔢 Sections & Topics Covered:

🔶 1. Digital Logic Gates (with Truth Tables)

• AND Gate (x = A · B)
• OR Gate (x = A + B)
• NOT Gate (x = A′)
• XOR Gate (Exclusive OR: x = A⊕B)
• NAND Gate (x = (AB)′)
• NOR Gate (x = (A + B)′)
• XNOR Gate (Exclusive NOR: x = A′B′ + AB)

📝 Sinhala explanations under each gate explain behavior in simple terms.

📐 2. Boolean Laws (Purple Section)

Includes laws like:

• Annulment Law: A·0 = 0
• Identity Law: A + 0 = A
• Complement Law: A + A′ = 1
• Idempotent Law: A + A = A
• De Morgan’s Theorem:
  • (A + B)’ = A’·B’
  • (A·B)’ = A’ + B’

📊 Example simplification of:
(A + B)(A + C)
→ Simplified to A + B·C, step-by-step using laws.

💻 3. Circuit Diagrams

• Visual illustrations of logic gate circuits
• Chip diagrams like:
  • 7404 Hex Inverter
  • 7402 Quad 2-input NOR
• Example CPU internal logic structure

🔩 4. Integrated Circuit (IC) Types

• Analog IC
• Digital IC
• Mixed-signal IC
• RF IC
• Power IC
• System-on-Chip (SoC)
