Problem 3:
Build the circuit using your logic kit. Note the suggested guidelines on the course
web page on how to construct a circuit using your logic kit. Before you begin wiring, write the pin
numbers from the IC (74HC00) on your circuit diagram.
No major issues were encountered in the design of the circuit. I created a sketch that looked like
this:
44
Then, I wrote the pin numbers from the IC (74HC00) on the circuit diagram.
I tested one of the NAND inputs to ensure that it was working as I expected it to. Then, I wired
up the NAND gate on my breadboard and attached leads to connect my input-output board to
the circuit. The result is shown in the next question.
Problem 4:
Test your circuit by wiring the inputs to switches and the output to an LED.
I tested each of the four (4) cases in the truth table. The cases are shown beginning on the next
page.

question from DIGITAL LOGIC DESIGN
TOPIC : Designing Combinational Logic
You are designing a water level circuit using 74ALS151 (8 to 1 Multiplexer IC)* When input is 0000 that means tank is empty.* When input is 1111 that means tank is full.* When input is below 5, that means water level is low.* So, make a circuit using 74ALS151 Multiplexer IC that shows a "low water" indicator light(by setting an output L to 1) when the water level drops below level 5.

NOTE: I need full complete solution and correct. Thanks you so much. Please help me!!
1. Implement the logic function
F(A, B, C) = AB' + BC + A'C' using 3x8 Decoder.
2. Implement the logic function
F(A, B, C) = AB' + BC + A'C' using multiplexer.
3. Design a combinational circuit with three inputs, x, y, and z, and three outputs, A,
B, and C. When the binary input is 0, 1, 2, or 3, the binary output is one greater than
the input. When the binary input is 4, 5, 6, or 7, the binary output is two less than the
input. Implement your design using multiplexer.

Consider the circuit below. The switches are controlled by
logic variables such that, if A is high, switch A is closed,
and if A is low, switch A is open. Conversely, if B is high,
the switch labeled is open, and if B is low, the switch
labeled is closed. The output variable is high if the output
voltage is 5V, and the output variable is low if the output
voltage is zero.

I know that logic gates are in fact consist of transistors but i wasn't expected to see regular electronic in the assignment sent by my teacher. Anyway... the question start from discuss you can ignore the others
