Design a Digital combinational logic circuit using logic gates that has 4 inputs and 2 outputs. The circuit:
i. Turns on a Red LED if its input is a multiple of 2. (i.e., 0, 2, 4, 6, 8 …..)
ii. Turns on a Green LED if its input is a multiple of 3. (i.e. 0, 3, 6, 9)

- Draw the truth table for the circuit, bearing in mind that this circuit has 4 inputs and 2
outputs, meaning your truth table should have 16 rows and 6 columns.

-The order of the truth table columns should match the order of your switches. Thus the
right most column of the truth table (LSB) must be the Right most switch and similarly the
MSB must be the Left most switch.

- Draw the circuit schematic.
legend, pin numbers, resistor values etc.

    Digital design question. Combinational logic & building blocks. 9.1 Voting circuit. Using combinational building blocks such as adders, comparators, mul- tiplexers, decoders, encoders, and arbiters, as well as logic gates, design a circuit that accepts five three-bit one-hot numbers and outputs the three-bit one-hot number that occurred most often on the inputs. Ties can be broken in any manner. For example, if the inputs are 100, 100, 100, 010, and 001, the output will be 100

    Why can't we design a combinational digital logic circuit to control a light so that the light changes state any time its "push-button" switch is pressed? (Press and release the button, and the light changes state. Press and release again, and the light changes state again.) Try to list as many properties this circuit needs to have that we cannot model as you can!
