In this paper, the transfer functions related to one-dimensional (1-D) and two-dimensional (2-D) filters have been theoretically numerically investigated. The finite impulse response (FIR), as well infinite (IIR) are main 2-D which More specifically, methods like Windows method, bilinear transformation design of from appropriate 1-D using optimization techniques presented.

We present an optical waveguide technology for low-loss, compact and tunable planar integrated optical devices. Examples of devices realized in this technology include finite and infinite impulse response (FIR and IIR) filters and optical switches. © 1999 Optical Society of America OCIS codes: (130.3120) Integrated optics devices, (130.3130) Integrated optics materials

Signal processing engineers recognize two main classes of filter: finite impulse response (FIR) and infinite (IIR), each with distinct properties. The Prism is a new filter type that combines the best both: numerical stability linear phase FIR together low-cost calculation IIR. Here, we show how to build ultranarrowband filters containing over one billion samples (taps) using sequence Prisms. W...

This paper presents the implementation of two stage FIR (Finite Impulse Response) decimation filter using system generator and it is compared with single stage implementation of FIR filter for WiMAX Application. FIR filter with decimation factor M is subdivided into two decimation factors M1 and M2. The two different FIR filters are designed with different coefficient values and different sampl...

This paper presents a class of Infinite Impulse Response (IIR) filters which have approximately Linear Phase response in their pass bands. The new filters provide better magnitude response and worse phase linearity for a given order and transition bandwidth than previous designs. They can then be used as an alternative to those designs when we want some degree of phase linearity but the magnitu...

This work looks at optimizing finite impulse response (FIR) filters from an arithmetic perspective. Since the main two arithmetic operations in the convolution equations are addition and multiplication, they are the targets of the optimization. Therefore, considering carry-propagate-free addition techniques should enhance the addition operation of the filter. The signed-digit number system is u...

This paper describes a class of orthogonal binomial filters that provide a set of basis functions for a bank of perfect reconstruction (PR) finite impulse response quadrature mirror filters (FIR QMF). These binomial QMF’s are shown to be the same filters as those derived from a discrete orthonormal wavelet transform approach by Daubechies. These filters are the unique maximally flat magnitude s...

Abstract This paper describes a class of orthogonal binomial filters which provide a set of basis functions for a bank of perfect reconstruction Finite Impulse Response Quadrature Mirror Filters (FIR-QMF). These Binomial QMFs are shown to be the same filters as those derived from a discrete orthonormal wavelet approach by Daubechies [13]. The proposed filters can be implemented very efficiently...

The Finite Impulse Response (FIR) filters are widely used in many Digital Signal Processing (DSP) applications. For these applications, the low power, less area, high speed and low complexity FIR filter architectures are required. The researchers have proposed many FIR filters to meet the above design specifications. This paper is focused on the some efficient reconfigurable FIR filter architec...
