With diagrams compare and contrast the relative advantages and disadvantages of digital transmission over analogue transmission in modern communication systems. There are main types of transmission that are used by two different forms of signals from one computer to another computer and they are:> Analogue Transmission> Digital Transmission Analogue Transmission An analogue transmission has no break in the signal and the movement along the sine wave will never stop. So therefore the analogue transmission is continuous. The waves fluctuate (rise or fall) a certain amount of times per unit of time this type of fluctuation over time is called frequency. Frequency is measured in hertz, this means the large amount of fluctuations the higher the frequency. The frequency will then translate into higher notes. The low frequency will produce low deep notes. This signal also fluctuates in its loudness. The loudness is called amplitude. A low volume has low amplitude. In...
