A B.Tech Digital Electronics syllabus typically covers number systems, Boolean algebra, logic gates, combinational and sequential circuits, and logic families. It also delves into flip-flops, timing circuits, and may include topics on programmable logic devices. Specific details can be found in university or college course outlines, often available as PDF documents. 

Here's a more detailed breakdown of typical topics:

1. Number Systems and Codes:

• Binary, Octal, Hexadecimal, and Decimal number systems.
• Interconversion between number systems.
• Binary-coded decimal (BCD), Gray code, Excess-3 code, and other codes.
• Code conversion and error detection/correction codes (e.g., ASCII, EBCDIC).
• Binary arithmetic (addition, subtraction) and complement representation. 

2. Boolean Algebra:

• Basic logic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR) and their truth tables.
• Universal gates (NAND, NOR).
• Laws and theorems of Boolean algebra.
• De Morgan's theorem.
• Minterms, maxterms, Sum-of-Products (SOP), and Product-of-Sums (POS) forms.
• Karnaugh Maps (K-maps) and simplification techniques.
• Don't-care conditions. 

3. Logic Families:

• Introduction to different logic families (RTL, DTL, TTL, ECL, CMOS, etc.).
• Comparative study of logic families based on characteristics like speed, power consumption, and noise immunity.
• Basic circuit diagrams and performance characteristics of each family.
• Wired logic and open collector outputs. 

4. Combinational Logic Circuits:

• Adders (half adder, full adder).
• Subtractors.
• Multiplexers and demultiplexers.
• Encoders and decoders.
• BCD to 7-segment decoders. 

5. Sequential Logic Circuits:

• Latches (SR latch).
• Flip-flops (SR, JK, D, T, Master-Slave, Edge-triggered).
• Timing diagrams and circuit analysis of flip-flops. 

6. Other Potential Topics:

• Programmable Logic Devices (PLDs).
• Memory elements (registers, counters).
• Digital circuit design and analysis.
• Applications of digital circuits in various fields.
