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.

Static Hazard 1 and One Circuit Problems?

I read about Static Hazard. We know Static 1-hazard is: Input change causes output to go from 1 to 0 to 1. My note covers a Circuit as follows: My notes says: When B=C=D=1, for any changes in A values, it's probable to have Static Hazard 1. But I…
