Which term describes the operation that emphasizes the leading edge and deemphasizes the remaining video?

• A. COAC
• B. AGC
• C. Limiter
• D. FTC

Answer: (D)

The operation being described is a time-domain shaping that boosts the early part of the signal while reducing the later portion. This is commonly called front-time control (FTC). By emphasizing the leading edge of the video, the initial return stands out more clearly, helping to detect targets and suppress trailing clutter or noise that arrives later in the frame. Automatic gain control would adjust amplitudes across the entire video rather than favoring the start, and a limiter would simply clip peaks without shaping the time envelope. The other term listed isn’t the standard designation for this edge-emphasizing process, so FTC best fits the description.
