Design of Cascade-Form IIR Filters with Powers-of-Two Coefficients Using Mixed Integer Linear Progra - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium

چکیده
We propose an optimal design method for digital IIR filters with powers-of-two coefficients. This method is based upon the formulation of a linear optimization problem that minimizes filter’s complexity for given specifications. It is shown that by taking the logarithm to the transfer function of cascade-form IIR filters, the design problem becomes linear and can be solved by mixed integer linear programming (MILP). Design examples are presented to demonstrate the efficiency of the proposed method.

OPTIMUM PRE- AND POSTFILTERS FOR QUANTIZATION - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
We consider the optimization of preand post filters surrounding a uniform quantizer such that the mean square error due to quantization is minimized. Unlike some previous work, the postfilter is not restricted to be the inverse of the prefilter. With no order constraint on the filters, we present closed form solutions for the optimum preand post filters. Using these optimum solutions, we obtain...

In many problems, such as the analysis of electrical circuits, one has to deal with Differential-Algebraic Equations (DAE’s). Knowing their generic index is of interest for practical and numerical as well as for theoretical reasons. In this paper we give an algorithm that determines the generic index of the Circuit Equations of linear active electrical networks in polynomial time from tlie netw...
متن کاملPITCH DETERMINATION AND SPEECH SEGMENTATION USING THE DISCRETE WAVELET TRANSFORM - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
Pitch determination and speech segmentation are two important parts of speech recognition and speech processing in general. This paper proposes a time-based event detection method for finding the pitch period of a speech signal. Based on the discrete wavelet transform, it detects voiced speech, which is local in frequency, and determines the pitch period. This method is computationally inexpens...
متن کاملA SUBTHRESHOLD-CMOS CHAOTIC OSCILLATOR - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
This paper reports on the design of a subthreshold-CMOS chaotic oscillator based on Chua's circuit. The circuit is autonomous and generates chaotic signals from three state variables in a manner analogous to a Chua circuit. Previous CMOS IC versions of the Chua circuit operate above threshold and make use of capacitors over 200 times larger than the subthreshold design. Also, this design is bas...
متن کاملA NEW SYSTOLIC ARCHITECTURE FOR FAST DCT COMPUTATION - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
This paper presents a fast algorithm along with its systolic array implementation for computing the 1-D Npoint discrete cosine transform (DCT), where N is a power of two. The architecture requires log,N multipliers and can evaluate one complete N-point DCT every N clock cycles. It possesses the features of regularity and modularity, and is thus well suited to VLSI implementation. As compared to...
