Best suited for audio and video transmission.īest suited for Computing and digital electronics.Īnalog signal processing can be done in real time and consumes less bandwidth. Less affected since noise response are analog in natureĭigital hardware is flexible in implementation.Ĭan be used in analog devices only. More likely to get affected reducing accuracy Subjected to deterioration by noise during transmission and write/read cycle.Ĭan be noise-immune without deterioration during transmission and write/read cycle. Samples analog waveforms into a limited set of numbers and records them. Human voice in air, analog electronic devices.Ĭomputers, CDs, DVDs, and other digital electronic devices.Īnalog technology records waveforms as they are. Uses discrete or discontinuous values to represent information Uses continuous range of values to represent information

Comparison chart Analog versus Digital comparison chartĪnalog signal is a continuous signal which represents physical measurements.ĭigital signals are discrete time signals generated by digital modulation.
