Analog Latch Reflex Blocks
At a Glance
Overview Two types of analog latch blocks are described in this chapter—edge latches and
level latches.
Edge latches latch an analog value on either the rising edge or falling edge of the
block’s trigger. The output from the block remains latched until the trigger causes
another input value to be latched. The output is always a latched value.
Level latches produce an output that is latched when the trigger is at one level (1 or
0) and unlatched when the trigger is not at that level.
