Questions tagged [circuit]

In a programming context, a circuit usually refers to a combination of logical operators to achieve a desired response. Use this tag to ask about basic logical implementations and loops you can't get your head around.

In a programming context, a circuit usually refers to a combination of logical operators to achieve a desired response. This could be implemented in hardware (see: electronic/electrical engineering) but in software the key issue is the logic.

Use this tag to ask about basic logical implementations and loops you can't get your head around.

Logical operators include AND, OR, NOT, NAND and NOR gates, and judicious combinations of these can be used to construct just about any possible structures.

How to mininize expression using boolean algebra?

Here is expression that we have to minimize with boolean algebra: y = /A/B/C/D + /A/B/CD + /AB/CD + A/B/C/D + A/B/CD + A/BC/D + A/BCD. I know little bit about that, please help!!! The answer is /A/CD + /B/C + A/B
