Sampled Data System
When the signal or information at any or some points in a system is in the form of discrete pulses. Then the system is called discrete data system. In control engineering the discrete data system is popularly known as sampled data systems.
Sampling Theorem
A band limited continuous time signal with highest frequency fm hertz can be uniquely recovered from its samples provided that the sampling rate Fs is greater than or equal to 2fm samples per seconds.
