How do we "know" that the J-K flip flop only changes on the rising edge, if we don't have the timing diagram?

@outcastoredwall Some JKFFs change on the rising edge, some change on the falling edge. It depends on their internal circuitry. When looking at the schematic symbol, a falling edge triggered FF is usually indicated by a bubble/circle drawn right at the clock input.

What does toggle mean???? 

[tarbidian]

@hello838 it means to either change from a '0' to a '1' or from a '1' to a '0'

[outcastoredwall]

Also, aren't most J-K flip flops usually master slave? So they change when the clock is low?

dude.. i <3 u. You saved my assignment.

Thanks. Subscribed.

@bassie52 it's called digital circuitry

[bassie52]

@tarbidian It looks very diffirent in real life. Also, how is this style of cirquitery called?

[tarbidian]

@bassie52 yes, redstone can be used to build digital circuits (like the JK and T flip flops) in Minecraft

[bassie52]

Is Red Stone based on this?
