In the case of telephony, when we speak into a handset, our voice is converted into current, or voltage fluctuations. While analog communication is limited by the speed and distance of its method, digital communication can be transmitted over any network. At the receiving end an approximation (analog) of the original information is presented. The transmission of the data is done by the intermediary of a carrier wave, a simple wave whose only goal is to transport the data by changing one of its characteristics (amplitude, frequency, or phase), it is the reason for which the analog transmission is generally called transmission by modulation of a carrier wave. #analogueTransmission #lineCoding #blockCoding #digitalTransmissionthis video cover the analogue and digital transmission and conversion. An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. inventory analysis project; wow portal to oribos from covenant; how to spot fake energizer batteries. However, most communications media are not digital. The polarity of each pulse determines whether it is positive or negative. Until the early 1980s the bulk of long-distance transmission was provided by analog systems in which individual telephone conversations were stacked in four-kilohertz intervals across the transmission banda process known as frequency-division multiplexing (FDM).
