dc.description.abstract본 논문에서는 효율적인 2-D FIR 노치필터 디자인 방법을 제안한다. 필터의 임펄스응답을 효율적으로 계산할 수 있는 Chebyshev 다항식의 확장하고 주파수대역에서 bandstop 필터 형태를 보이는 Zolotarev 다항식을 Chebyshev 다항식으로 확장 적용하여 1-D DC FIR 노치필터를 설계하는 방법, frequency shifting, 그리고 임펄스응답의 2-D convolution을 이용하여 효율적인 2-D FIR 노치 필터 설계 방법들을 제안한다. 시뮬레이션을 통하여, 설계된 2-D 노치필터의 특성을 검증한다.; In this thesis, a new approach for the efficient design of 2-D FIR notch filters using 1-D DC-notch FIR filter, frequency shifting, and 2-D convolution. The proposed approach utilizes a generating function to design the notch filter using the graphical representation of Zolotarev polynomials. In particular, a 2-D FIR notch filter is designed by using a closed-form formula for filter coefficients along with frequency shifting and 2-D convolution. Simulation results show that the proposed approach yields improved quality of images with sinusoidal interference and provides a practical and efficient design procedure for the realization of a sharp FIR notch filter of low order, satisfying the given filter specification.-
