متن کاملOn Error-Spectrum Shaping in State-Space Digital Filters
A new scheme for shaping the error spectrum in state-space digital filter structures is proposed. The scheme is based on the application of diagonal second-order error feedback, and can be used in any arbitrary state-space structure having arbitrary order. A method to obtain noise-optimal state-space structures for fixed error feedback coefficients, starting from noise optimal structures in abs...
متن کاملRecursive Digital Filters
1 Recursive Digital Filters A digital filter is the implementation of an algorithm that computes an output sequence of numbers from an input sequence of numbers. The algorithm may be implemented (or realized) using a general-purpose computer running software, a special-purpose computer such as a Digital Signal Processor (DSP) running software, or on special purpose hardware such as an Applicati...
متن کاملOn the Direct Design of Selective Recursive Digital Filters
In this paper a generalization of direct design of di erent types of recursive digital lters is proposed. This method allows that the coe cients of the polynomials containing the poles of transfer function to be determined in closed form, directly in digital domain. These lters can not be obtained using transforms from continuous domain. Cuto slopes of these lters has been also investigated.
متن کاملAll-Pole Recursive Digital Filters Design Based on Ultraspherical Polynomials
A simple method for approximation of all-pole recursive digital filters, directly in digital domain, is described. Transfer function of these filters, referred to as Ultraspherical filters, is controlled by order of the Ultraspherical polynomial, ν. Parameter ν, restricted to be a non-negative real number (ν ≥ 0), controls ripple peaks in the passband of the magnitude response and enables a tra...
