When I was in my engineering there are many topics on Analog and Digital devices. I love the topics very much. Analog is the process of converting audio or video or data in to electric pulses where as Digital is the process of converting the data in to ‘o’ and ‘1′ and transferring the data. The digital technology breaks your voice signal into binary code which is a series of 1s and 0s and transfers it to the other end where another device. The clarity of digital data is very good when compared with Analog data. Digital offers better sound quality than Analog. Many companies are trying to use Digital devices and technologies in many areas.
