Answer:

Radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis because radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and use the data for processing and analysis. These radio light waves, that are raw analog signals, are converted into digital signals to create and distinguish delicate details in the universe.
