Analog devices made digital are more cost effective.

Analog devices have been popular since the 1970s. They include analog phones, clocks, radios, home entertainment equipment, PA systems, automotive radios, and much more. In today's age, many analog devices are being transformed into digital devices. That is why it is necessary for analog to digital converters for the varying devices out there. It is sometimes more cost effective to convert analog to digital rather than implementing new digital devices in many automobiles, home theater systems, televisions, etc. An example is taking an analog television and converting the signal to digital using a digital cable feed through a digital box. It allows consumers who cannot afford to go out and buy a brand new expensive digital television to enjoy the same digital quality for a fraction of the cost by using their local digital or analog cable service.
