telecommunications and electronics, a self-clocking signal is one that can be decoded without the need for a separate clock signal or other source of synchronization...

A clock or chronometer is a device that measures and displays time. The clock is one of the oldest human inventions, meeting the need to measure intervals...

clock signal is a special digital signal that is used to synchronize many digital circuits. The image shown can be considered the waveform of a clock...

sourced clock signal arrives at different components at different times due to gate or, in more advanced semiconductor technology, wire signal propagation...

electronics, a word clock or wordclock (sometimes sample clock, which can have a broader meaning)[further explanation needed] is a clock signal used to synchronise...

driven by a clock signal and, because of its periodic nature, has an unavoidably narrow frequency spectrum. In fact, a perfect clock signal would have...

dedicated clock signal (known as clocking, pulsing, or strobing). Clocking causes the flip-flop either to change or to retain its output signal based upon...

these early synchronous CPUs ran at low clock rates compared to modern microelectronic designs. Clock signal frequencies ranging from 100 kHz to 4 MHz...

design a clock domain crossing (CDC), or simply clock crossing, is the traversal of a signal in a synchronous digital circuit from one clock domain into...

MIDI beat clock, or simply MIDI clock, is a clock signal that is broadcast via MIDI to ensure that several MIDI-enabled devices such as a synthesizer or...
