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.

About analog devices: Analog is a way of transmitting information through electronic signals of frequency or amplitude. It has continuous waves that move up and down that is indiscrete. Common analog devices are clocks, radios, old cellular phones, etc. The analog signal is most often used to day in telephone lines, radio broadcasts, and television broadcasts. The two common methods of analog modulation are amplitude modulation (AM) and frequency modulation (FM). Analog is very different from a digital signal because it has a constant transmission whereas a digital signal starts and stops. A digital signal is more finite and reliable than an analog signal. Also, a digital signal is made up of zeros and ones and an analog signal can handle many different values.

Analog to digital converters are necessary for communicating between a dial up connection and PC.

Those who choose to use a Dial-Up connection are in need of an analog device that can convert analog to digital. The device is necessary in order to provide the handshaking that takes place between the phone line and the computer. The phone line is an analog signal and the computer is a digital signal. The modem will process the digital information going out and the analog information coming in at speeds each can handle. The faster the modem the faster the conversion of data. However, always remember that different times of day are more hectic than others for data transmission so regardless of the speed of the analog to digital converter the speeds will vary tremendously.
