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 ...

Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
The jam signal or jamming signal is a signal that carries a 32-bit binary pattern sent by a data station to inform the other transmitting stations of the collision and that they must not transmit. [9] [10] The maximum jam-time is calculated as follows: The maximum allowed diameter of an Ethernet installation is limited to 232 bits. This makes a ...
In telecommunications, signal regeneration is signal processing that restores a signal, recovering its original characteristics. [ 1 ] The signal may be electrical, as in a repeater on a T-carrier line, or optical , as in an OEO optical cross-connect .
A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal's carrier wave and the receiver's local oscillator for the purpose of coherent demodulation.
Meter data management (MDM) refers to software that performs long-term data storage and management for the vast quantities of data delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head-end servers managing the data collection in advanced metering infrastructure (AMI) or automatic meter reading (AMR) systems.
