What is the difference between a cellular phone and a telephone?

Answer 1

In an analog phone, the mechanical energy of sound (speech) is picked up by a microphone (mic) and converted into an (analog) electrical signal. This signal is then put through whatever electronics stages are required (if any) to get the signal onto a phone pair for transmission to the receiver.

In a digital cell phone, the mic picks up the sound and converts that into an analog electrical signal. That analog signal is then sent to an electrical stage called an analog-to-digital (A to D) converter. Once the signal is digitized, it can be treated as a data string and amplified and broadcast (to the cell hub) as such. An incoming call is a digital data string that is D to A converted in the phone and then the newly recovered analog signal is made to be heard by the user.

The difference between the two is the conversion and re-conversion (analog to digital and digital to analog) in the digital cell phone.

Answer 2

What is the difference between analog and digital? Between analog and digital is as a technology analog is the process of taking an audio or video signal the human voice and translating it into electronic pulses digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of 1s and 0s.
