Create a list of 3 technologies that have gone from analog to digital. What was the reasoning for each conversion?
Answer:
The Digital Revolution, also known as the Third Industrial Revolution, is the shift from mechanical and analogue electronic technology to digital electronics which began anywhere from the late 1950s to the late 1970s with the adoption and proliferation of digital computers and digital record keeping that continues to the present day.Implicitly, the term also refers to the sweeping changes brought about by digital computing and communication technology during (and after) the latter half of the 20th century. Analogous to the Agricultural Revolution and Industrial Revolution, the Digital Revolution marked the beginning of the Information Age
Cell phones became as ubiquitous as computers by the early 2000s, with movie theaters beginning to show ads telling people to silence their phones. They also became much more advanced than phones of the 1990s, most of which only took calls or at most allowed for the playing of simple games.Text messaging existed in the 1990s but was not widely used until the early 2000s, when it became a cultural phenomenon.
The turning point of the revolution was the change from analogue to digitally recorded music.[6]During the 1980s the digital format of optical compact discsgradually replaced analog formats, such as vinyl records and cassette tapes, as the popular medium of choice
telecommunication: Analog-to-digital conversion
In transmission of speech, audio, or video information, the object is high fidelity—that is, the best possible reproduction of the original message without the degradations imposed by signal distortion and noise. The basis of relatively noise-free and distortion-free telecommunication is the binary signal. The simplest possible signal of any kind that can be employed to transmit messages, the binary signal consists of only two possible values. These values are represented by the binary digits, or bits, 1 and 0. Unless the noise and distortion picked up during transmission are great enough to change the binary signal from one value to another, the correct value can be determined by the receiver so that perfect reception can occur
digital sound recording
method of preserving sound in which audio signals are transformed into a series of pulses that correspond to patterns of binary digits (i.e., 0’s and 1’s) and are recorded as such on the surface of a magnetic tape or optical disc. A digital system samples a sound’s wave form, or value, several thousand times a second and assigns numerical values in the form of binary digits to its amplitude at any given instant. A typical digital recording system is equipped with an analog-to-digital converter that transforms two channels of continuous audio signals into digital information, which is then recorded by a high-speed tape or disc machine. The system uses a digital-to-analog converter that reads the encoded information from the recording medium and changes it back into audio signals that can be used by the amplifier of a conventional stereo sound system.
