We live in an analog world. There are an infinite amount of colors, noises and smells. This common theme among all of these analog signals are their infinite possibilities.
Analog signals are continuous, therefore there are no breaks or interruptions. An example of an analog signal is sound. When a person sings a descending note, others are able to recognise the notes gradually changing pitches, however unable to identify the specific time when changing notes.
Digital signals are not continuous and use particular numerals that symbolises information. Regarding to sound, a sound wave is shown as a sequence of numerals that represent pitch and volume. In a digital recording of a descending note, instead of an entire long sound, there is an abundance of shorter sounds. This allows the person to see at what time the pitch or volume changes.

IMPORTANT FACTS: Digital is better for transmitting information over far distances. Analog is transmitted through cords. Analog are less noise resistant than digital. |
