Analogue Vs Digital Signalling 0.0 / 5 ? ComputingHardware componentsASWJEC Created by: TinaCoolBeansSargCreated on: 23-11-14 22:55 Analogue Signals are continuously variable, meaning they can take a range of values and any value in between 1 of 6 They take up more bandwidth to transfer signals They are not high tolerance as mistakes can easily be made, e.g. (0.00564 could easily be 0.00563) 2 of 6 Used in earlier technologies such as older televisions signals and telephone networks, in order to vary the frequency of the signal Greenhouses may use analogue signal readers to take numerical data such as the temperature 3 of 6 Digital These are discrete signals that contain two states. 4 of 6 These states help to represent numbers, letters, images, sound and programs. This is high tolerance as the two states cannot be mistaken. 5 of 6 This signal occupies a smaller bandwidth and is commonly used for radio and television broadcasting, as more programs can be squeezed in for viewers Digital watches use this signals and digital thermostats 6 of 6
