Analysis and Synthesis of 8 bit binary full adder by cascading two IC 7483 chips

INSTRUCTION

  1. Apply high to VCC and low voltage to ground (GND)
  2. For all the combinations of the 8 bit inputs A (A7A6A5A4A3A2A1A0),B (B7B6B5B4B3B2B1B0) verify that the LEDs are ON or not.
  3. Enter binary input A=10011011 (Decimal value is 155), B=10011011 (Decimal value is 155). Check output S=100110110 (Decimal value is 310)(C8 S7S6S5S4S3S2S1S0).
  4. Enter other input combination of A and B.
  5. Note: Red button symbolize as Low (L), Green button symbolize as High (H).
