During the early 21st century there was a big switch in the signals that were sent to and from devices and sources. This is when analog signals were replaced by digital signals. When this change was made people were not fond of the new type of signal, but overtime digital signals took over everyplace analog signals were used. Now more than a decade later we now understand digital signals are more reliable and efficient
When looking and understanding an analog signal one discovers that the signal is a continuous wave that represents different instructions according to its amplitude and wavelength. This continuous wave contains a lot of information that is sent from a source to a receiver. When trying to store all of this information, it takes up lots storage and space. Analog signals, when being copied, are prone to interference which changes the sound or leaves out parts of it due to corruption. On the other hand, digital signals use a code made of 1s and 0s. Because of this, when we store this data it is far easier to copy it from the source. With less information, you can store it on smaller devices, and because the data is made of 1s and 0s it can be copied infinitely without interference and is exactly the same as the source or device it was copied fr...
