Practice question · True or false
A combinational circuit can give different outputs for the same inputs, depending on what came before.
Hints
- What would it need to remember?
- No memory element, no history.
Show the answer
False
Why
False. With no storage element there is nothing to hold history, so the output is a pure function of the present inputs. Adding feedback through a latch is exactly what creates state and makes a circuit sequential: and that is the dividing line between the two families.
