Detection of noise in high pass IIR digital filters

Role of Filters in electronic devices is evident in this modern era. Filtering is a term that is used in most DSP applications to pass specific frequencies and reject other ones. There is a wide range of application areas of digital filters including image processing, voice, and video and data communication. A large number of techniques are used to design IIR filters. This paper´s idea is to design, analyze and compare performance of Chebyshev I, Chebyshev II and Butterworth IIR filters using MATLAB FDA tool. Noise free signal will be rendered at the output of filter. Further effect of different parameters such as order, type of filter and cut off frequency are filter.
