A/D
A/D stands for Analog-to-Digital. It is the process of converting analog signals, such as sound or light waves, into digital signals that can be processed by a computer. In space and astronautical engineering, A/D conversion is used in various applications, such as in the design of sensors and instruments for spacecraft. These sensors and instruments measure physical quantities, such as temperature, pressure, and radiation, and convert them into digital signals that can be transmitted to the spacecraft's computer for analysis and control. A/D conversion is also used in the design of communication systems for spacecraft, where analog signals, such as voice and video, are converted into digital signals for transmission and reception.
