51Controller-area network — (CAN or CAN bus) is a computer network protocol and bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer.It was designed specifically for automotive applications but is now also used… …
52Spectral efficiency — Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is… …
53MLT-3 encoding — (Multi Level Transmit) is a line code (a signaling method used in a telecommunication system for transmission purposes) that uses three voltage levels. An MLT 3 interface emits less electromagnetic interference and requires less bandwidth than… …
54Proximity-1 Space Link Protocol — is a short haul delivery protocol designed to establish a two way communications link between a lander and an orbiter, negotiate data rate and communications mode, and reliably deliver data during short orbiter to surface contacts. Developed by… …
