This lecture focus to present Digital Filters. Inside signal processing, digita filter is a process that performs mathematical operations using a sampled, discrete-time signal to lessen or enhance certain areas of that signal. This is as opposed to the other major style of electronic filter, your analog filter, which can be an electronic routine operating on continuous-time analog signals. Digital filter system usually consists of an analog-to-digital converter to be able to sample the enter signal, followed by way of a microprocessor and some peripheral components for instance memory to retail store data and separate out coefficients etc. Here also briefly focus on: Frequency Response, FIR versus IIR, Difference Equations and FIR Filters Properties and Design.
