介绍了一种可用于语声信号处理的高性能EllipticBireciprocal结构低通波数字滤波器实现的集成设计方法。充分利用先进半导体工艺的速度，采用硬件复用技术，整个电路的所有运算分化为单步的加减在一带超前进位链的ALU单元上分时进行，由此节省硬件耗费。该滤波器在时域及频域上的性能已在C模拟器上经过验证，能够达到纹波系数小于0．00007dB，阻带衰减大于112dB。
This paper introduces an integrated design method of high performance EllipticBireciprocal lowpass digital filter for speech signal processing. Take full advantage of advanced semiconductor technology, the use of hardware multiplexing technology, the entire circuit into a single-step addition and subtraction of all operations in the ALU unit ahead of the chain chain time-sharing, thus saving hardware costs. The performance of the filter in the time domain and frequency domain has been verified on a C-simulator to achieve a ripple factor of less than 0.00007 dB and a stop-band attenuation of greater than 112 dB.
