okay. when we talk we are using...
analog. our voices are coming in through continuous waves. but a computer can only recognize digital signals. even though the output you hear appears continuous, it is actually an enormous number of discrete signals.
the phones microphone which picks up all the noise around us. by removing unwanted noise, it is converting analog to digital.
digital. the computer recognizes our digital signals and converts these signals into a smooth -- or analog -- output.

Explanation:

This is a task to order the conversation segments to logically explain analog and digital signals. First, define analog using human speech as an example. Then, explain how devices convert analog to digital via microphones and noise removal. Next, note that computers only understand digital signals. Finally, explain how digital signals are converted back to analog for output.
