A straightforward design method is delivered for bandpass wave digital lattice filters satisfying arbitrary amplitude and linear phase specifications. The optimality and efficiency of this method are ensured by two sources. On the one hand, the approximation is carried out directly without the need

Two different approaches are introduced for the design of non-prototype ladder and lattice wave digital filters (WDFs) exhibiting arbitrary amplitude in the baseband (passband, transition band and stopband) and linear phase in the passband. The first approach is based on the phase correction of a mi
In the literature there are many papers that deal with the combined approximation of loss and phase (and or group delay) characteristics. 1 -12 Unfortunately, many of these approaches are non-optimum in the sense that the filter specifications can be satisfied with a lower-degree filter. Optimal sol
The non-linear problem of simultaneous approximation of the magnitude and phase by an FIR digital filter is studied. Usually this problem is solved indirectly by solution of the complex Chebyshev approximation problem of the frequency response of the filter, which can be described as a linear or non
An efficient, simple and reliable design method is introduced for bandpass wave digital lattice filters exhibiting arbitrary loss responses. The main feature of this method is that the approximation is straightforward. Thus it is carried out without the need to apply frequency transformation techniq
