|
What does a latch have to do with RS flip-flops?

RS flip-flops require an external signal to change its condition.
|
|
|
What is an asynchronous circuit?
|
One that can change conditions any time an input changes.
|
|
|
What is a synchronous circuit?
|
One that can only change when the clock pulse is present.
