We propose several minimax design methods based on WLS and Karmarkar’s algorithms for optimally designing FIR Nyquist filters with low group delay and 2-D lowpass filters. In addition, the circuit of FIR filters must have the multipliers and this makes the computation speed slow. Therefore, we use CORDIC algorithm to discretize filter coefficients, and won’t need any multipliers in circuit implementation. From the examples presented in each chapter of this thesis, we show the effectiveness of the proposed design techniques. 李枝宏 2007 學位論文 ; thesis 69 zh-TW |
