The two diagrams ellucidate the differences in the development of the analogue mobile phone and a digital phone.
In general, the earliest form had features like a black /white display which was improved to a full-colour display in the contemporary phone. The analogue one had a function select button which was improved to extra functions in the digital phone. Only the earphone feature was constant for both analogue and digital phone.
To begin with, the analogue mobile phone measured 130mm in length and 50mm in width and weighed 150g. Also at the top right was the ear phone port. In addition, the screen gave a black/ white display and it had a function select button at the middle.
In contrast, the digital mobile phone is lighter(70g) and smaller(90mm by 40mm) as compared to the analogue one. In addition to this, the screen gives a full-colour display as opposed to the analogue phone which has a black/white display. Furthermore, it has an extra feature of a camera with video capability.
