The edges of the signals can shift around in a real-world electronic system for various reasons. If the clock and the data signal are shifted relative to each other, this may increase or reduce the timing margin; as long as the data signal changes before the setup time is entered, the data will be interpreted correctly.
These are used to supply timing signals in complex electronic systems that require multiple frequencies or clock phases. For example, most computers require independent clocks for processor timing, disk I/O, serial I/O, video generation, Ethernet I/O, audio conversion, and other functions. [3]
An output timing distribution component that utilizes the timing signals from the timing-generation component to create multiple DS1 and CC output signals; A performance-monitoring (PM) component that monitors the timing characteristics of the input signals; An alarm interface that connects to the central-office (CO) alarm-monitoring system
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
A digital timing diagram represents a set of signals in the time domain. [1] A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing ...
The term is most often used to describe digital data transmission, in which case the entire signal is suitable for clock recovery. For instance, in the case of early 300 bit/s modems, the timing of the signal was recovered from the transitions between the two frequencies used to represent binary 1 and 0. As some data might not have any ...
Clock skew (sometimes called timing skew) is a phenomenon in synchronous digital circuit systems (such as computer systems) in which the same sourced clock signal arrives at different components at different times due to gate or, in more advanced semiconductor technology, wire signal propagation delay. The instantaneous difference between the ...
A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
