Related to delaying: satisfying
in automatic control systems, a phenomenon that consists in the fact that when the input signal of a system or device begins to change, the output signal begins to change only after a certain time interval, called the delay time. The component of the delay time determined by the final intrinsic rate of propagation of the signal is called the transport delay. Delay may also be caused by the inertia of the system. In electronic simulation equipment, delay is created artificially in delay circuits, which retard the reproduction of the signal by some predetermined time interval. Such delay is used in the simulation of many technological processes associated with matter transfer or power transmission.
ii. In radar operations, the ground distance from a point directly beneath the aircraft to the beginning of the area of a radar scan.
iii. The electronic delay of the start of the time base used to select a particular segment of the total.
