Reason, creates complete theory and the method that continuous time signal is transformed under sampling theorem instructs discrete-time signal.
It is to say, only primary signal can be expressed by original analog signal sample value on series of discrete time coordinate point and not lose
Lose any information, since the expression of these concepts of ripple, waveform, signal is the change of various physical quantitys in objective world, the most just
It it is the carrier of the various information that modern society depends on for existence.Information needs to propagate, and lean on is exactly the transmission of waveshape signal.Signal exists
Its generation, change, each link of transmitting is likely to be due to environment and the existence of interference and distorts, even quite a lot of
In the case of, this distortion is the most serious, causes signal and entrained information thereof to be embedded in the middle of noise dearly.In order to
Filter these noises, recover signal originally, need to use various wave filter to be filtered processing.
