Complex Correction of Data Acquisition Channels Using FIR Equalizer Filters
The common conviction about FIR (finite impulse response) digital filters is that the number of necessary taps, to reach the same performance as provided by IIR (infinite impulse response) digital filters, is usually too large. Moreover, the standard FIR filter design algorithm (Remez exchange) allows the design of linear-phase filters only. Therefore, IIR filters are often preferred over FIR o...
متن کاملDesign of Discrete Coefficient FIR and IIR Digital Filters with Prefilter-Equalizer Structure Using Linear Programming
Optimal methods for designing multiplierless finite-impulse response (FIR) and infinite-impulse response (IIR) filters with cascaded prefilter-equalizer structures are proposed. Assuming that an FIR filter consists of a cyclotomic polynomial (CP) prefilter and an interpolated second order polynomial (ISOP) equalizer, in the proposed method, the prefilter and equalizer are simultaneously designe...
متن کاملEqualization of Data Acquisition Channels Using Digital Filters
The possibility of the compensation of amplitude and phase errors of data acquisition channels is investigated. The complex passband error can be signiicantly reduced by an appropriate digital lter, as it is illustrated on the example of a dynamic signal analyzer. The aspects of IIR and FIR equalizers are studied: it turns out that for the given anti-aliasing lter (Cauer lter, order 11) an FIR ...
متن کاملDetermine Optimal Coefficients of IIR Digital Filters using Simulated Annealing
This paper determines coefficients of infinite-impulse response (IIR) using Simulated Annealing (SA). IIR filter is essentially a digital filter with Recursive responses. Since the error surface of digital IIR filters is generally nonlinear and multimodal, global optimization techniques are required in order to avoid local minima. In this paper heuristic way for the designing IIR filters is pre...
