A new practical design approach for minimum-phase FIR or IIR filters, setting out from a high dimensionality FIR linear-phase prototype is described. The novelty of this technique lies in overcoming the inherent problem of finding the roots of a high order polynomial with repeated and/or very closely clustered roots 相似文献

The Commission of European Communities (CEC) has put in place an interlocking set of initiatives aimed at enhancing the skillsbase European industry will require in order to sustain a competitive posture. One of these programs, COMETT II, is aimed at continuing education for small and medium enterprises. Another program, TEMPUS, aims to increase links between western and eastern Europe, and strongly focuses on academic interchanges and updating undergraduates/postgraduate curricula. DSP-forum, a COMETT II partnership between several European industrial firms and educational establishments, which primarily concentrates on short industrial training courses at a multiplicity of sites is discussed. Eleven partners in seven countries are currently involved with DSP-forum. Four additional partners presently complete the network of cooperating groups under TEMPUS sponsorship (primarily for development and validation of courseware and labware suitable for supporting remote interactive learning of DSP topics) 相似文献

The Milne-Thomson circle theorem is extended to give a simplegeneral expression for the image system in an elliptical cylinderintroduced into an otherwise specified unbounded potential flowwhich contains no singularities in the region to be occupiedby the ellipse. This image system is used to obtain an expressionfor the corresponding source-sink surface singularity distributionon the ellipse, thus providing new benchmark test cases forsource-sink solutions as obtained numerically by a panel method.Several typical examples are given to illustrate the generaltheoretical approach. 相似文献

Fractional-sample delay in discrete-time systems is often provided by special FIR filters which are asymmetric about mid-sequence. Here we preserve the appeal of sine-sequence fractional delayers (simplicity and single-parameter delay tuning) by devising a two-term raised-cosine window which delivers fractional-delay filters comparable to the best obtainable by highly regarded optimisation approaches 相似文献
