FIR Filter Design

This was a relatively easy assignment as the MATLAB function fir1() directly generates the required filter based on the given specifications. The only task was to decide the appropriate window function based on the given stop band attenuation, as taught in the lecture.

  1. FIR filters are very useful because they can be used to obtaining linear phase response.

  2. Window method is widely used because different window functions can be used for different specifications of filter design.

  3. Yes, MATLAB does make it much simpler to use and analyse different Window functions with variety of inbuilt functions.

  4. Why not use 'C' as the other experiments?
