In this paper, we propose the design method for over sampled filter banks which satisfy the perfect reconstruction and linear phase properties. Moreover, we consider the design methods for both orthogonal and biorthogonal ones. We first derive the conditions of perfect reconstruction and linear phase for both biorthogonal and orthogonal filter banks. Then, we present the design methods for both cases. Finally some design examples are shown.

The unique relationships between Arithmetic spectra of switching functions and the spectra of Boolean AND, OR and XOR of such functions are presented. Essential operations used in classification and optimization of logical network have been also analyzed in Arithmetic spectral domain. Some of such operations involve input and output negations and permutations of input variables. By using presented methods, the computation of the total spectrum of any Arithmetic expression for an equivalent switching network is straight forward, and many of the equivalent operations in Arithmetic domain are simpler than their Boolean counterparts which should increase practical interest in usage of Arithmetic transform for design automation tools.

An adaptive analog notch filter is proposed for applications requiring high frequency adaptive signal processing. Based on a log filter circuit topology, this filter design suggests new circuitry for the implementation of analog adaptive filters. Simulation results demonstrate that the filter is capable of rejecting a sinusoid, and with a second notch filter section attached, is capable of rejecting a pair of sinusoids. The circuit design and the adaptation method are described.

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 the 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.

This paper presents a unified synthesis method for dealing with generalized asynchronous circuits which comprise specifications of both Asynchronous Finite State Machines (AFSMs) and Signal Transition Graphs (STGs). By comparing the similarities and differences of two different synthesis methods, we describe algorithms and techniques underlying our CAD system for automating the design of the generalized asynchronous circuits based on the well-developed synthesis procedures of Huffman-modeled asynchronous circuits. Experimental results show that the developed system, implemented in C, can handle concurrence and sequencing of STGs and fundamental mode operation of AFSMs at the same time, therefore, it allows for a more natural and compact specification of asynchronous behavior.

The design of an analog circuit, particularly to accommodate component tolerances, can benefit immensely from insight into the complex relations between designable parameters and circuit performances. Such insight is currently acquired via tedious exploration, but this exploration can now be significantly enhanced by an interactive tool called the Influence Explorer. Its graphical presentation of precalculated data relating parameters and performances allows fluent qualitative exploration, including the discovery of important trade-offs and correlations. The Influence Explorer also provides a smooth transition to quantitative design decisions, including those involved in tolerance design.
