Analog vs Digital
by Caitlyn Shea
A signal is something that represents information (It can be a comment, sound, or series of numbers and letters). An analog signal is a signal with properties like frequency and amplitude-they can change continuously depending on the changes in the original format. It is a continuous signal that represents physical measurements and has no breaks or interruptions. Examples of analog signals are a telephone, film camera, and record. A telephone works by an electric current converted into a sound wave by the receiver. The sound is heard almost the same as the sound generated on the other line. A film camera works by a plastic film and light, the photograph that comes out is known as an analogy of a scene. Lastly, a record is an analog signal carved into a grooved dish. All of these are analog because the waves are not changed into numbers- that would be digital.
