Activity 2.1.3 AOI Logic Implementation
In this activity, I learned how to implement AOI Logic circuits from a logic expression. The logic expressions were in either Sum-Of-Products or Product-Of-Sums form and I had to translate them. After filling out the activity, I designed the circuit in Multisim 14.0. From there, I used the circuit I made on Multisim to help as a guide while I was trying to recreate the circuit on the breadboard. I found the correct chips and looked up a diagram to find out what each input does on the chips. After a little bit of troubleshooting and rewiring, the circuit was finally able to work and light up the LED under the certain conditions.
Activity 2.2.2 Universal Gates: NAND Only Logic Design
In this activity, I was given the conditions for a voting booth and alarm at a voting station. I had to implement NAND only combinational circuits for both the booth and the alarm. I had to start off creating the regular AOI circuits and then re-implement them using only 2-input NAND gates. I then compared the 2 circuits and found that the NAND one was a lot more efficient. After doing a little research, I also found that the NAND circuits were a lot more cost efficient compared to regular AND gates. Using the circuit I designed in Multisim 14.0, I was able to breadboard the circuit and allow the LED (the alarm at the voting station) to go on once the right conditions were met.
