Virtual Lab Mastery: Digital Electronics Simulation & Design

Design a full adder by deriving sum as a xor b xor c and carry as the or of three product terms, using a truth table, k-map, and logic diagram.

Design a full adder in the digital electronics simulator by wiring inputs A, B, and C through xor and and gates to produce sum and carry, then verify with leds.

Design a full subtractor for subtraction, derive the difference as a xor b xor c, and borrow as a' c + a' b + b c, then implement the logic.

Learn to implement a full subtractor with xor, and, or, and not gates using three inputs a, b, c and verify difference and borrow with leds.

Explore multiplexers, the data selector that routes one of multiple inputs to a single output using select lines, with a 4:1 mux design example.

Design and simulate a 4 to 1 multiplexer with four inputs and two select lines using and, or, and not gates; verify with an LED and the truth table.

Explore how a demultiplexer, or data distributor, routes a single input to one of multiple outputs via select lines.

Explore the implementation of a 1-to-4 demultiplexer using two select lines, an input, not gates, and four and gates, with leds in a virtual lab to verify the truth table.

Design a one-bit magnitude comparator in digital electronics to yield A=B, A<B, and A>B from a truth table, using xnor and and gates.

Implement a one bit magnitude comparator with inputs A and B, generating outputs for greater than, equal, and less than using not gates, an xor/xnor, and gates, verified with LEDs.
