ESC-CS301 ESC Digital System

Digital Systems (ESC-CS301):

1. Logic gate: A device that performs basic logical functions like AND, OR, NOT.
2. Combinational circuits output based only on inputs; sequential circuits depend on current inputs and previous states.
3. A flip-flop is a memory element that stores one bit of data.
4. Boolean algebra is a mathematical framework for binary operations, essential in digital circuit design.
5. A multiplexer selects one input from multiple inputs based on selection lines.
6. A decoder converts encoded inputs into a distinct output line, often for data selection.
7. A full adder adds binary numbers and accounts for carry from previous sums.
8. Digital signals are discrete, while analog signals are continuous.
9. A shift register shifts stored data bits in a particular direction (left or right).
10. A clock signal synchronizes the timing of operations in digital circuits.
11. Binary-coded decimal (BCD) represents each decimal digit with its binary equivalent.
12. A latch stores a bit until it is actively changed.
13. Flip-flops include types like SR, D, JK, and T, each with different functions.
14. A Karnaugh map (K-map) simplifies Boolean expressions visually.
15. An ALU performs arithmetic and logical operations within a CPU.
16. RAM is volatile, temporary memory; ROM is non-volatile, permanent storage.
17. A synchronous counter counts in sync with a clock signal.
18. Propagation delay is the time for an input change to affect the output.
19. Two’s complement is a binary number representation for positive and negative numbers.
20. A DAC converts digital data to an analog signal.
