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.
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 ...
LaTeX, which is popular in typesetting mathematical documents, has several packages for drawing circuit diagrams. Advantages: Professional looking output (same quality as in commercial textbooks). Free and open source software. Transparent source that is diffable. Mathematical formulas and text are nicely typeset.
An active circuit used for such a purpose is known as a repeater. In a CMOS integrated circuit, the repeater is often a simple inverter. Reducing the delay of a wire by cutting it in half and inserting a repeater is known as repeater insertion. The cost of this procedure is the additional new delay through the repeater itself, plus power cost ...
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 ...
By contrast, static timing analysis computes the delays of entire paths, using delay calculation to determine the delay of each gate and wire. There are many methods used for delay calculation for the gate itself. The choice depends primarily on the speed and accuracy required: Circuit simulators such as SPICE may be used. This is the most ...

A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. 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 ...
