Using building blocks such as binary adders, comparators, multiplexers, decoders, encoders, and arbiters as well as logic gates, design an 8x2 popularity circuit – a circuit that accepts eight two-bit numbers and outputs the number of times each of the four numbers appears on the input.
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! Reminder: a "combinational digital logic circuit" takes one or more boolean inputs and feeds them through...
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...
Design a combinational circuit that adds 1 to 3-bit unsigned binary number and produces an unsigned binary result. Do the following: (1) determine the number of inputs/outputs, (2) write the truth table, (3) simplify the output functions by using maps and (4) draw the logic diagram by using AND OR and NOT gates. Show the truth table, the map, and the logic diagram. Do NOT use adders.

1. Using only half adders, design a four-bit incrementer circuit (a circuit that adds 1 to a four- bit binary number). 2. Using only 2-to-4 line decoders with enable, construct a 4-to-16 line decoder. 3. Using a decoder and external gates, design the combinational circuit defined by the following three Boolean functions: F = x'y'z' + x2 F2 = xy'z' + x'y F3 = x'y'z + xy
Design a combinational logic circuit which has one output Z and a 4-bit input ABCD representing a binary number. Z should be 1 iff the input is at least 5, but is no greater than 11. Use one OR gate (three inputs) and three AND gates (with no more than three inputs each). Using K-map, find min SOP and min POS form for the outputs W, X
2. Design a digital logic circuit to convert part of the output code from part 1. to a binary signal. Use CMOS gates. (hint, the simpler you can get the logic, the less work you will have). You must draw the circuit with transistors In Out DUIi 0111 011 0011 010 0001 001

The Counter A counter is a hardware circuit whose output counts in sequence, changing at each rising has a three-bit out rolls over" back to zero to count through the sequence again. We can d edge of a clock input signal. As an example,...
3) [9 marks] Using the combinational circuit design procedure discussed in the notes, design with a truth-table, simplify with K-maps, and draw the combinational circuit that accepts a 3-bit number and generates a 5-bit number output equal to 3X + 2 where X is the input number (if the input is 010 (2), the output should be (01000) 8 . Let the inputs be A, B, C and the outputs be V, W, X, Y, Z.
