Advantages of using DSP•data compression
•undistorted signal transmission
•security of data communications
• representation of signals in discrete-time format
• fast & convenient implementation of signal processing systems
•…
Problem (1)Problem (1)•How to use a digital signal to represent an
analog signal?
•How many samples are necessary?
•What happen if there are no enough samples?
Problem (2)Problem (2)
• If the signal is contaminated, how to remove or mitigate the undesired signal component?
