i have project in my logic circuit, these were the asynchronous using basic logic gates (74ls04,74ls08,74ls11,74ls21,74ls32) and timer circuit using ne555 ic. please help me to create the schematics and if possible, solve also the karnaugh map and the boolean simplification.




guys, it uses two dual seven segments for the display and one triple seven segment for the addition result in the asynchronous.

 

What is the purpose of this logic? It's not clear from your post. What progress have you been able to make?

We can help with parts of the project you can't get to work, but we will not do the assignment for you.

 

it's about adder logic circuit using 74ls83 and 74ls47

i'm asking for the schematic diagram. pls help

 

Look at:-

It's all there!
