Answer:B
Which of the following types of communication is used by the HART protocol for digital data transmission?
A. Pulse Width Modulation B. Frequency Shift Keying C. Amplitude Shift Keying D. Phase Shift Keying
Explanation: HART protocol uses Frequency Shift Keying (FSK) for digital data transmission, which allows for reliable communication in noisy industrial environments.
