In many applications for every signal it is desired to design a filter for specific frequency so it is very time consuming to develop a different filter for every desired selective frequency. For overcome this problem, the current designing of filter is quite easy to develop a frequency selective filter with few changes and also to separate two or more. One more easy benefit of this filter designing is to select one or more frequencies at a time present in the composite signal. By using an above MATLAB programs determine the coefficients and plot the frequency response of FIR filter to meet the specifications
