S-2 Reconstruction filter Output IDSP-3.: The different blocks of this system are as follows: 1. S-2 shows that the basic elements of digital signal processing system Analog input Anti Aliasing x(t) filter Digital signal processor Sample and hold circuit Fig. This phenomenon is called as signal processing.īasic Elements of DSP and its Requirements: Fig. S-I, when we apply an input signal to the system, the system will process the signal and we get the expected response. System is nothing but physical device that performs an operation on a signal. System: System is associated with signals. This leads -to a simple definition of DSP.ĭefinition of DSP: DSP is defined as changing or analysing information which is measured as discrete sequences of numbers. Processing: To perform operations on data according to programmed instructions. Signal: A variable parameter by which information is conveyed through an electroic circuit.
