As shown in figure "B" in the illustrated block diagram of a central operating system configured for supervisory control, what is the function of the block "ANALOG (A-D MUX)"? EL-0094

Correct Answer: Option A — A high speed solid-state switching device called a multiplexer capable of scanning a large number of analog sensors in a short period of time and converting these to signals to digital values for processing by the CPU.

A multiplexer (MUX) is a high-speed switching device that allows a single Analog-to-Digital converter to process multiple sensor inputs sequentially. By rapidly scanning numerous analog signals, the MUX enables the CPU to monitor various engine parameters in real-time, ensuring efficient supervisory control of the vessel's machinery and operating systems.
