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.

What will be the circuit for the counter with oscillating 1s (1000, 0100, 0010, 0001, 0010, 0100)?

I have a basic understanding of custom counter. I know of a method to implement (8,4,2,1,2,4) counter i.e. using FSM, but I am not able to figure out how the circuit will get implemented?
