Setup time is the minimum amount of time the data input should be held steady before the clock event, so that the data is reliably sampled by the clock. Hold time is the minimum amount of time the data input should be held steady after the clock event, so that the data is reliably sampled by the clock. Aperture is the sum of setup and hold time ...
However, if the structure of the clock distribution network is known, different source register/destination register pairs may have different jitter parameters, and a different jitter value may be used for the hold constraint in contrast to the value for the setup constraint. For example, if the source register and destination register receive ...
A simple example of metastability can be found in an SR NOR latch, when both Set and Reset inputs are true (R=1 and S=1) and then both transition to false (R=0 and S=0) at about the same time. Both outputs Q and Q are initially held at 0 by the simultaneous Set and Reset inputs.
Hold time may refer to: In digital electronics, the minimum amount of time the data input should be held steady after the clock event for reliable sampling; see Flip-flop (electronics)#Timing considerations; The amount of time spent in a phone queue on hold (telephone) Hold Time, by M. Ward
In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time.

One of the first known examples of a shift register was in the Mark 2 Colossus, a code-breaking machine built in 1944. It was a six-stage device built of vacuum tubes and thyratrons . [ 5 ] A shift register was also used in the IAS machine , built by John von Neumann and others at the Institute for Advanced Study in the late 1940s.
