What happens to peak and null locate responses if signal distortion is present?

• A. They will match
• B. They will no longer match
• C. They will disappear
• D. They will invert signs

Answer: (B)

Peak and null locate responses depend on a clean, consistent signal. When distortion is present, the signal’s shape and phase get warped, so the point where the receiver sees a maximum (peak) is no longer the same location where it sees a minimum (null). That mismatch means the two cues don’t line up with each other, making the peak and null responses no longer match. Distortion can still leave both responses visible, but their positions won’t agree, and the readings become unreliable.
