41. Once the slave receives the beginning of the clock signal ( 1 ), it automatically freezes its current data. 42. The counter is preset to some initial count value, and counts down at each cycle of the clock signal . 43. The Synchronization Clock Interface routes MLVDS ( Multipoint Low-voltage differential signaling ) clock signals over multiple 130 ? buses. 44. In synchronous sequential circuits, the state of the device changes only at discrete times in response to a clock signal . 45. They are carefully designed to maintain the resonators motion at appropriate amplitudes and to extract low noise output clock signals . 46. Since the clock signal is distributed throughout the entire circuit it can consume a large percentage of the energy used. 47. Their technique used 2 inch Quadruplex videotape to record the signals along with a clock signal from an atomic clock. 48. Figure 7 shows a clock signal with its four stages and the effects on a cell at each clock stage. 49. This reduces the number of communication pins on the module to just two : a clock signal and a data signal. 50. A DLL can be used to change the phase of a clock signal ( a signal with a DRAM devices ).
