Which of the following is NOT listed as an operational technique to attain EMC?

• A. Increased transmitter power.
• B. Shielding, site selection, bonding/grounding, frequency management, time-sharing scheduling, filtering, and preventive maintenance.
• C. Filtering.
• D. Grounding.

Answer: (A)

In trying to achieve electromagnetic compatibility, the focus is on reducing interference and making equipment more immune to it. Practical operational controls that accomplish this include shielding, choosing sites wisely, proper bonding and grounding, managing frequencies to avoid clashes, time-sharing or scheduling to minimize simultaneous transmissions, filtering to block unwanted frequencies, and ongoing preventive maintenance to keep systems within specs. These measures directly limit emissions and improve resilience. Increasing transmitter power, on the other hand, tends to raise both emitted and conducted noise and can worsen EMC problems rather than solve them. It’s usually not used as a technique to attain EMC; it can even push a system past regulatory limits. The comprehensive list in the other option reflects the typical set of measures employed, with filtering and grounding as common, explicit examples. So the choice that involves simply upping transmitter power is not listed as an EMC technique.
