Smith at AT&T Bell Labs invent the charge-coupled device (CCD), transforming light into electric signals. The binary number system was refined by Gottfried Wilhelm Leibniz (published in 1705) and he also established that by using the binary system, the principles of arithmetic and logic could be joined. The Digital Revolution (also known as the Third Industrial Revolution) is the shift from mechanical and analogue electronic technology to digital electronics which began in the latter half of the 20th century, with the adoption and proliferation of digital computers and digital … Before a signal can be handled by digital electronics, it has to be converted into digital form.
