Thinking how best to describe a problem that I'm sure is simple to some but has confused the hell out of me!
OK, I have an analog circuit that I need to enable and bring up in a certain way.
So here's the truth table. Firstly there's an INIT and both inputs must be low to get an output.
Next the THEN phase when the TUNE input can change but the output must remain.
They must happen in this order. If the enable changes the output will (obviously) go low.
INIT
TUNE ENABLE OUTPUT
0 0 1
0 1 0
1 0 0
1 1 0
THEN
0 0 1
0 1 0
1 0 1
1 1 0
I've mused of logic combinations but cant suss it and I'm sure it's some kind of flip flop related cure.
Any ideas?
