What device converts the digital signals carried by the cable into analog signals compatible with the TV set?

• A. Set-top box
• B. Digital terminal adapter (DTA)
• C. Modem
• D. Tuner

Answer: (B)

When a TV that isn’t equipped to handle digital signals needs to display cable channels, you need a device that translates those digital channels into an analog form the TV can show. A digital terminal adapter is designed for this exact task: it takes the digital signals carried by the cable and outputs an analog signal suitable for an old-style TV with a coax RF input. That focused function makes it the best fit for getting analogue compatibility from digital cable. A set-top box can handle digital decoding and often outputs digital video via HDMI or other modern connections, which isn’t what an older TV needs. A modem is for internet data, not video. A tuner selects channels but doesn’t convert the digital stream into analog for a non-digital TV.
