Answer the following question in 3-4 complete sentences. How has digital technology changed television? Why is it an improvement?

Answer:

Digital technology changed television by replacing older analog signals with clearer digital signals. It made it possible to produce sharper images, better sound, and thinner flat-screen televisions such as plasma and LCD sets. Digital TV also allows for high-definition broadcasts and more channels or features. This is an improvement because the picture and sound quality are better and the equipment is more efficient and compact.
