Which of the following describes the use of vestigial sideband in analog fast-scan TV transmissions?

Amplitude Modulated (AM) signals naturally produce two identical sidebands. Because fast-scan video contains frequencies up to 4+ MHz, a standard double-sideband AM TV signal would take up an enormous amount of RF spectrum (over 8 MHz). To conserve spectrum, a technique called vestigial sideband (VSB) is used. One sideband is almost entirely filtered out (leaving only a small "vestige"), while the other is transmitted fully. This reduces the overall bandwidth while still preserving the fidelity of low-frequency video components, which are retained in the remaining vestigial portion.
