) Abstract: At present, there’re three methods to design FIR DF: window method, frequency samp- ling method and optimal design method
This paper uses that three methods to design and simulate various FIR DF based on MATLAB, and compares the characteristics of them
The result reveals that Chebyshev approximation method has a great deal of advantages including optimal frequency response and attenuate response, smooth pass band、forbidden band and narrow transition band under the same design order
