The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed of impulses in the medium. Analog delay lines are applied in many types of signal processing circuits; for example the PAL television standard uses ...
Basic fixed-threshold comparator and its derivatives - simple time delay relay and cascaded window monitor. To ensure fast turn-off transients, load resistor RL should provide on-state current of at least 5 mA [39] The simplest TL431-based comparator circuit requires a single external resistor to limit I CA at around 5 mA.

The timing diagram example on the right describes the Serial Peripheral Interface (SPI) Bus. Most SPI master nodes can set the clock polarity (CPOL) and clock phase (CPHA) with respect to the data. This timing diagram shows the clock for both values of CPOL and the values for the two data lines (MISO & MOSI) for each value of CPHA.
A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...
The first example gives the circuit for a 6th order maximally flat delay. Circuit values for z a and z b for a normalized lattice (with z b the dual of z a) were given earlier. However, in this example the alternative version of z b is used, so that an unbalanced alternative can be easily produced. The circuit is
Two dimensional tables [1] are commonly used in applications such as logic synthesis, placement and routing. These tables take an output load and input slope and generate a circuit delay and output slope. The values of the tables are usually computed using circuit simulators in a procedure referred to as characterization or standard cell ...
Lattice and bridged-T equalizers are circuits which are used to correct for the amplitude and/or phase errors of a network or transmission line. Usually, the aim is to achieve an overall system performance with a flat amplitude response and constant delay over a prescribed frequency range, [1]: 128 [2]: 679 by the addition of an equalizer. In ...
The digital delay generator is similar to a pulse generator in function, but the timing resolution is much finer, and the delay and width jitter much less. Some manufacturers, calling their units "digital delay and pulse generators", have added independent amplitude polarity and level control to each of their outputs in addition to delay and ...
