Can an analog tv receive a digital cable signal?

using two subcarriers and a main carrier signal

• audio subcarrier is frequency modulated with audio
• color subcarrier is phase modulated with chroma
• main carrier is amplitude modulated with sum of video and modulated audio subcarrier & color subcarrier; then lower sideband is suppressed by a filter.
• closed captions are serial ASCII encoded characters embedded in vertical blanking of video signal
