WebThis delay is the specified aperture delay that you are asking about. The aperture delay will not always be a constant across temperature and voltage but will vary, and it may vary from a minimum of 0.5ns on one device at one extreme of voltage and temperature to a maximum of 2ns on another device at the other extreme of voltage and temperature. WebThe Unit Delay block holds and delays its input by the sample period you specify. When placed in an iterator subsystem, it holds and delays its input by one iteration. This block is equivalent to the z-1 discrete-time operator. The block accepts one input and generates one output. Each signal can be scalar or vector.

WebControl loops typically have “sample and hold” measurement instrumentation that introduces a minimum dead time of one sample time, T, into every loop. This is rarely an issue for tuning, but indicates that every loop has at least some dead time. The time it takes for material to travel from one point to another can add dead time to a loop.
