Question

Illustrate in brief the term Setup time?

Answer 1

Setup time is a timing parameter related with Sequential Devices (for the simplicity hereafter just referring to the Flip Flop). The Setup time is employed to meet up the minimum pulse width need for the first (Master) latch makes up a flip flop is. Much simply, the setup time is the quantity of time which an input signal (to the device) should be stable (unchanging) before the clock ticks in order to guarantee the minimum pulse width and therefore ignores the possible meta-stability.
