Design of an FIR notch filter with arbitrary notch frequency by using a modified sampling kernel
K. J. Kim, S.W. Nam · IEICE Electronics Express · 2008
A new method of designing FIR notch filters with arbitrary notch frequency is proposed, where a modified sampling kernel is introduced and utilized along with a complementary filter concept. In particular, the proposed sharp notch FIR filter design provides a closed-form solution for filter coefficients, leading to further utilization for designing reconfigurable FIR notch filters.
