    I've got this question-what is the the triggering input of a Flip-Flop is called?
    Would it be "enable"

    It depends on your application but in logic applications its enabled.

    Cool thanks, also I'm stuck on this question too. "Show how a negative edge triggered D Flip-Flop can be formed using S-R Flip-Flop?"

    Any idea?
    Appreciate the help

    Flip flops are fun isn't it? Well D and RS are almost the same. Edge triggerings are related to data input at D flip flops.

    Depends on who is choosing the terms because there is no rigid, universally accepted terminology.

    If the trigger input is edge-sensitive it is often called a "clock" while if it is level-sensitive it is often called either a "write enable" or a "write strobe" (sometimes shortened to just "enable" or "strobe").

    There are a few ways to do this depending on if you want the output to appear immediately after the negative-going edge or if you want the output to appear on the following rising edge.
