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.
