My analog assignment

• Examples of analog signal :
• In sound recording, sound strike the diaphragm of a microphone which induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone , or the voltage produced  by a condesor  microphone.
• Radio and television are good examples of everyday uses of filters. When a channel is changed on an analog television set or radio, an analog filter is used to pick out of carrier frequency on the input signal. Once it's isolated, the televison or radio information being broadcast is used to form the picture and/or sound. Another common analog system is an electric guitar and its amplifier. The guitar uses magnet with a coil wrapped around it (inductor) to turn the vibration of the strings into a small electric current. The current is then filtered, amplified and sent to a speaker in the amplifier. Most amplifiers are analog because they are easier and cheaper to make than making a digital amplifier.
