Digital Lab Trainer

Digital Lab Trainer Features:

Digital Lab Trainer

The DIGITAL LAB is intended for elementary as well as advance training of digital electronics. The digital lab covers regular digital circuits by solder-less interconnections on breadboard and as well as compatible with all optional modules through use of 2mm brass terminals and patch cords. Various clock generators, logic level input/output indicators and DC regulated power supplies etc. are in-built. The unit housed in attractive enclosure is supplied with mains cord, patch cords, Instruction manual and Component Set.

Experimental Coverage:

  1. Logic gates operation
  2. To verify De-morgan’s theorem with boolean logic equations
  3. Binary to Gray code conversion
  4. Gray code to Binary conversion
  5. Binary to Excess-3 code conversion
  6. Binary Adder and Subtractor
  7. Binary Multiplier
  8. EX-OR gate implementation
  9. Application of EX-OR gate
  10. Johnson Counter
  11. To verify the dual nature of Logic Gates
  12. Study of Flip-Flops RS, JK, D&T
  13. Multiplexer and Demultiplexer
  14. 4 Bit Binary up and down counter
  15. Study of 8 to 3 Line Encoder
  16. Study of 3 to 8 Line Decoder
  17. Study of Shift Register (SIPO)
  18. CMOS-TTL Interfacing
  19. Study of Crystal oscillator
  20. Study of pulse stretcher circuit
