Analog and Digital Transmission Telecommunications

Analog TransmissionDigital TransmissionConversion Codecs and ModemsAn analog wave form (or signal) is characterized by being continuously variable along amplitude and frequency.In the case of telephony,for instance,when you speak into a handset,there are changes in the air pressure around your mouth.Those changes in air pressure fall onto the handset,where they are amplified and then converted into current,or voltage fluctuations.Those fluctuations in current are an analog of the actual voice patternhence the use of the term analog to describe these signals (see FigSee more on informitTelecommunications Technology FundamentalsCircuitsChannelsLines and TrunksVirtual CircuitsA circuit is the physical path that runs between two or more points.It terminates on a port(that is,a point of electrical or opticalinterface),and that port can be in a host computer (that is,a switching deviceused to establish connections),on a multiplexer,or in another device,asdiscussed later in this chapter.In and of itself,a circuit does not define the number of simultaneousconversations that can be carried; that is a function of the type of circuit itis.For example,a simple,traditional telephone circuit is designed to carrySee more on informitmodem Definition,Development, Facts BritannicaModem,any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.A modem also receives modulated signals and demodulates them,recovering the digital signal for use by the data equipment.AFL - Fiber optic cable,transmission and substation AFL offers fiber optic cable,transmission and substation accessories,outside plant equipment,connectors,fusion splicers,test and inspection equipment,training services.AFL - Fiber optic cable,transmission and substation AFL offers fiber optic cable,transmission and substation accessories,outside plant equipment,connectors,fusion splicers,test and inspection equipment,training services.
