【摘要】 本文描述了具有有效计算结构的分析－合成滤波器组的有效设计算法。其特点是在cosine调制滤波器组的设计上。得到滤波器组在计算和设计上是高效的，它可广泛应用在分频段编码（SBC）上。这里利用了快速Hartley变换，从而大大减少了运算量，为用在DSP超大滤波器组上奠定了基础。更多还原

【Abstract】 This paper presents an effective design algorithm for analysis - synthesis filter banks withcomputationslly efficient stracture. The resulting filter banks are very efficient in terrns of compulationalrequirements and are relative easy to design. They are very useful in a great number of applications. for examplesub-band coding. Here a realization using the Fast Hartley transform of the number of operations is describedso that it is possible to implement in DSP with very large filter banks.更多还原
