چکیده
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.

Unified design algorithm for complex FIR and IIR filters
In this paper, a general filter design norm is proposed with the intent of producing a unified design algorithm for all types of filters— FIR, IIR and 2-D FIR with complex specifications. The Chebyshev, least squares, and constrained least squares problems become special cases because this norm uses a convex combination of the 2-norm and the Chebyshev norm. The primary benefit of this new probl...
متن کاملOn fast FIR filters implemented as tail-canceling IIR filters
We have developed an algorithm based on synthetic division for deriving the transfer function which cancels the tail of a given arbitrary rational (IIR) transfer function after a desired number of time steps. Our method applies to transfer functions with repeated poles, whereas previous methods of tail-subtraction cannot [1]. We use a parallel state-variable technique with periodic refreshing t...
متن کاملApplying FIR and IIR Digital Filters over Video Image Processing
Digital Video is a stream of still images called frames, which are moved such that it gives an illusion of dynamics of the objects present in the image. Video image processing is basically processing of frames and updating frames with a minimum frame rate of 16 per second to give an illusion of motion picture. The objective of the research is all about the development of high throughput image p...
متن کاملImplementing FIR and IIR Digital Filters Using PIC18 MCUs
INTRODUCTION The Microchip PICmicro® PIC18 family of microcontrollers are popularly known for their logic and controlling functions. In addition, these microcontrollers have builtin hardware multipliers and multiple file pointers. These features, along with the built-in analog-to-digital converter (ADC), make PIC18 microcontrollers a competent choice for applications where logic and controlling...
متن کاملDesign of first-order differentiator utilising FIR and IIR sub-filters
In this paper, we propose a novel approach for constructing the first-order differentiator. It has been shown recently that an efficient Finite Impulse Response (FIR) wideband differentiator can be synthesised when applying the multirate and Frequency-Response Masking (FRM) techniques. The overall signal processing task is shared between a very loworder differentiator and an FIR half-band filte...
