charlies1902 said:I think my thinking is wrong on these 3 questions. I'll start with the first question on the attached pic.
Here is what I'm thinking:
For question 33:
X=0 R=0, then R changes to 1. Basically, Clear changes from 1 to 0.Which means do NOT clear. Thus Q=1 (the inverse of X)?
This is obviously not the answer. Which part of my logic is erroneous?
charlies1902 said:Oh I see. Thanks for explaining this.
So for #34:
X=1 R=1
R=1 => Clear=0 (do nothing)
We don't know the previous Q value, so how would we know what Y or Z is?
I guess we don't?
then R changes to 0
so Clear=1, so Q=0=Y, thus Z=1.
For #35:
X=1 R=1 => Clear=0 (does nothing for the whole time even if the input X changes).
Since we don't know what Q was before, it's uncertain.
Am I understanding this correctly?
Preset switches are used to set a specific value or condition in a circuit, while clear switches are used to reset or clear the circuit to its default state.
Preset switches typically have a fixed value that is set by the manufacturer. When the switch is turned on, it connects that value to the circuit. This allows for precise control of the circuit's parameters.
No, preset switches cannot be reprogrammed as they are set by the manufacturer. However, some preset switches may have adjustable settings or values that can be manually changed.
Clear switches are used to reset a circuit back to its default state. This can be useful for troubleshooting or preparing the circuit for a new set of instructions.
It is important to follow the manufacturer's instructions and safety guidelines when using preset and clear switches. These switches can control high voltages and currents, so proper precautions should be taken to avoid electric shock or damage to the circuit.
