Calculator buttons using flip-flips to store numbers as binary?

AI Thread Summary
Using flip-flops to store binary numbers for a calculator is feasible, as they can hold the binary representation of inputs like 5 (0101) using NAND flip-flops. The discussion suggests that pressing buttons 0-9 would store the corresponding 4-bit values in four NAND flip-flops. However, the exact design intentions are unclear, leading to a suggestion to consult digital electronics resources, such as Mano's book, for guidance on creating a simple microprocessor. The conversation emphasizes the importance of clarity in design goals for effective implementation. Understanding digital logic fundamentals is crucial for this project.

Is it possible to use flip-flips to store numbers inputted, for example if i input 5, current will go to 4x nand flip flip and store 0101 and the next digit to be calculated, any ideas on this?

That is how it is done.
 
I want to use it like a calculator, when you press 0 to 9 button 4 bits will be stored in 4x nand flipflops
 
What you want to make is not clear. I guess you want to design a simple microprocessor. In that case read a digital elec book like mano.
 

Thread 'What happens if shielded cable has short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
