Questions tagged [circuit-diagram]

A circuit diagram (also known as an electrical diagram, elementary diagram, or electronic schematic) is a simplified conventional graphical representation of an electrical circuit.

Circuit diagrams are pictures with symbols that have differed from country to country and have changed over time, but are now to a large extent internationally standardized. Simple components often had symbols intended to represent some feature of the physical construction of the device.

Common schematic diagram symbols (US symbols)

Difference between D Latch Schematic and D Flip Flop Schematic

I heard that the main difference between latch and flip flops is that latches are asynchronous while flip flops are edge triggered which makes sense. But when I check out their shematic they seem pretty much same. Here is the design of a dlatch from…

How to convert (abc) to a NAND gate?

Using DeMorgans I get: ~~(abc) // ~ is the not. My problem is when I try to build the circuit the NAND gate takes only 2 inputs. So how would I split it for 3? If it was an AND gate I would just use two and the equation would be: (a AND b) AND…

Logic-based light system

I need to develop a system that turns on the red light when all three switches are off, and turns on the orange light when any two out of three switches are off. The red light part is already sorted with a simple NOR gate. I'm having trouble with…

How to convert a 3 input AND gate into a NOR gate?

I know that I can say convert a 2-input AND gate into a NOR gate by simply inverting the two inputs because of DeMorgan's Theorem. But how would you do the equivalent on a 3-input AND gate? Say... ____ A___| \ B___| )___ C___|____…

Graph databases for modeling specific domain

With a normal 'graph database' the data is broken up into nodes and edges, and there isn't much of a restriction/schema between the connections. With this, it seems great for modeling straightforward graphs where the relationships are relatively…
