Question

which of the following statements best describes the operation of an up/down synchronous counter? the counter can count in either direction, but must continue in that direction once started. in general, the counter can be reversed at any point in its counting sequence. the counter can be reversed, but must be reset before counting in the other direction. the count sequence cannot be reversed, once it has begun, without first resetting the counter to zero.

Answer 1

An up/down synchronous counter can count in both directions and can be reversed at any point without needing a reset.

Step-by-step explanation:

The question concerns the operation of an up/down synchronous counter. The correct statement that best describes its operation is that the counter can count in either direction and can generally be reversed at any point in its counting sequence. Unlike asynchronous counters, synchronous counters are designed in such a way that their count can be controlled and reversed at any point without needing to reset the counter first.
