How often the analog signal is measured. A common rule is to sample at least 10 times the frequency of the signal being measured.

: On an Arduino board, analog inputs are used to read values from sensors like potentiometers or photoresistors. The analogRead() function typically converts a voltage (0–5V) into a digital integer ranging from 0 to 1023.

: You can find detailed wiring guides for analog inputs on the Arduino Documentation Industrial Automation (PLC) : In systems like the Siemens S7-1200 Go to product viewer dialog for this item.

The number of bits used to represent the signal; higher resolution (e.g., 12-bit or 16-bit) provides more precision.
