The back repeater has latched the front repeater in a power-off state (shown

Comparators
The redstone comparator increases or decreases an output signal according to the strength
oftheinputsignal.Comparatorscancheckthecontentsofachest,hopper,furnace,dropper,
dispenser, juke box, and brewing stand or compare the relative storage of each and then
trigger another function such as making a railcart with the hopper move to another loca-
tion for unloading. See
Figure 9.9
.
I'll show a few more useful scenarios in the examples
that follow. The comparator requires nether quartz, which is only available in The Nether
