Abstract
This paper investigates the new approach to FIR filter design based on nonuniform frequency sampling. This method generates the nonuniform samples in passband and stopband separately using Gaussian function. For the generated nonuniform sample, the desired frequency response values are generated using ideal filter characteristics. Then, taking its nonuniform IDFT gives the required filter coefficients. The proposed method is compared with existing methods like uniform frequency sampling and optimal filter design method and results show that the investigated approach has a better advantage over uniform frequency sampling and Parks–McClellan method with regard to the frequency response of designed filter.
