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)

Implementing a Mux 2:1 using only XNOR, NAND, OR with maximum of 4 gates

I had been given a task to implement a mux2:1 using only these given gates: XNOR NAND OR. The inputs would be a, b and sel (select). The output should be z (there's no enable input). The maximum number of gates to be used is 4 (and only those 3…

Multithreaded Graph Traversal

I have a graph which represents a big circuit network. Each wire/device can either be "active" (it is - through some path of wires and devices - connected to power) or "inactive" (it isn't connected to power). No ground wires or voltages are…

Simplifying logical expression

Is there a way to reduce this logical expression? I map out the circuit design to logical expression but I can't find a way to reduce it more, I feel that there is a way to do so. I've tried De Morgan's law but that only changes one statement not…

Purpose of variables for multiplexer

I am to implement an 8-to-1 multiplexer using the variables m(1,3,5,6,8,13). The function is: F(A,B,C,D) = A′B′C′D + A′B′CD + A′BC′D + A′BCD′ + AB′C′D′ + ABC′D I feel I have a basic idea of how multiplexers work, however I'm not entirely sure what…

simplifying the boolean expression (a*'b*'c) + ('a*'b*c) + ('a*b*'c) + (a*'b*c)

I'm having a lot of trouble on the last part of a boolean expression I'm trying to simplify. so far I got (where multiplication is AND and addition is OR): (a * 'b * 'c) + ('a * 'b * c) + ('a * b *'c) + (a * 'b * c) (a * 'b * 'c) + (a * 'b * c ) +…

Map boolean function to cells

I need to map a known Boolean expression to AND,OR,NOT gates optimally (or almost optimally :D ), i.e. do the cell-library binding of the expression (aka technology mapping). The expression has 4 input variables (A,B,C,D) and produces 4 output…

Circuits , Hazards/Karnaugh diagram || Can a Karnaugh-Vetch diagram consisting of 2 variables x and y even contain a hazard?

i dont understand completely but to me it seems like there cant be a problematic/hazardous path. So its about hazards that can occur in a half-adder circuit with Inverters XORs and Ands. Cant get to create the structural term and diagram. Would…
