sequential/combinational systems. Questions range from basic gate operations to designing
circuits, as noted in the test pattern and interview feedback.

 Binary, octal, decimal, hexadecimal number systems
 Conversions between number systems.
 Binary arithmetic: addition, subtraction, 1’s and 2’s complement.
 Codes: BCD, Gray code, Excess-3 code, ASCII

1.2 Logic Gates


 Basic gates: AND, OR, NOT, NAND, NOR, XOR, XNOR.
 Universal gates: NAND and NOR implementations.
 Truth tables, Boolean algebra, and logic expressions.
 Simplification using De Morgan’s theorems.

1.3 Boolean Algebra and Minimization:


 Boolean laws and theorems.
 SOP (Sum of Products) and POS (Product of Sums) forms.
 Karnaugh maps (K-maps) for simplification (2–4 variables).
 Don’t care conditions.

1.4 Combinational Circuits:


 Adders: half adder, full adder, carry look-ahead adder.
 Subtractors: half subtractor, full subtractor.
