This is the mathematical foundation of digital circuits. You will face questions requiring base conversions and simplification of logical expressions.
1. Number Systems
Be comfortable converting between Decimal (Base 10), Binary (Base 2), Octal (Base 8), and Hexadecimal (Base 16).
- Hex to Binary: Each hex digit represents 4 binary bits (e.g., A = 1010).
- Octal to Binary: Each octal digit represents 3 binary bits (e.g., 7 = 111).
2. Logic Gates
Memorize the truth tables for AND, OR, NOT, NAND, NOR, XOR, and XNOR.
NAND and NOR are 'Universal Gates' because any logical function can be implemented using only NAND or only NOR gates.
3. Boolean Algebra Laws
Key laws to memorize for expression simplification:
- De Morgan's Theorems: (A+B)' = A' . B' and (A.B)' = A' + B'
- Absorption Law: A + AB = A and A(A + B) = A
Final Thoughts
Mastering the concepts discussed above is a stepping stone towards your ultimate goal. Remember that consistency is key. Keep revising the core topics, practice as many questions as you can, and always analyze your mistakes to ensure continuous improvement.
