What is Enable and Disable in Logic Gates?
In: Engineering
Can not give a 100% answer becasue it does depend on the case …but…
If you have a set of digital inputs to a set of gates, the output will only change ( respond) due to the inputs when “enabled”.
This is helpful if the inputs take time to change or settle into the correct states. The system can ignore all of the changes until they are all valid.
Let’s say you have a basic demonstration system with 4 input switches and an enable switch.
If the system is Enabled while you change the 4 inputs, the output will change (depending on the logic) as the 4 input switches are set. However if you turn off the enable ( disable) – and then you change the inputs, and then enable the system, then the output goes from the Previous State – to the Final state at once.
