Definition of Clock-edge triggering
Check what you remember
Read the wording for your board, then hide it and explain Clock-edge triggering in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Flip-flop states update on clock edges, so Q changes only on the active clock edge rather than immediately with its input.
