| 内容記述 | A simultaneous frequency- and time-domain approximation method for discrete-time filters is proposed in this paper. In the proposed method, transfer function coefficients are divided into two subsets,X_{1}andX_{2}, which are employed for optimizing a time response and a frequency response, respectively. Frequency and time responses are optimized through the iterative Chebyshev approximation method and a method of solving linear equations, respectively. At therth iteration step, the maximum frequency response error, which appeared at the(r - 1)th step, is minimized, andX_{2}^{(r- 1)}becomesX_{2}^{(r)})cdot X_{1}^{(r)}is obtained from linear equations includingX_{2}^{(r)}as a constant. The frequency response at the rth step is evaluated using the above obtainedX_{1}^{(r)}andX_{2}^{(r)}. This means the optimum time response is always guaranteed in the frequency-response approximation procedure. A design example of a symmetrical impulse response shows the new approach is more efficient than conventional methods from the filter order reduction viewpoint. | |||||
