Magnitude and Phase Response Analysis of Low Pass Fir Filter Using Blackman And Blackman Harris Window Techniques
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
A digital signal processing is a main branch of electronics. It is concerned with the representation by sequence of number or symbol and the processing of these signals. Dsp have many more applications which are useful in our life i.e. Telecommunication, image processing, speech processing, medical diagnostic instrumentation and signal filtering etc. Signal filtering is the most important application of dsp. In this process we can remove all the unwanted background noise and interference. In this paper we are concentrating on low pass fir filter design by using blackman and blackman harris window techniques. By the comparative analysis of both the window technique we conclude that, the blackman window design having better result in pass band region and show more attenuation in stop band region with compare to blackman harris window technique.
