Analytical approach to the multiband filter synthesis and comparison to other approaches
For electrical filter designers, this provides a more efficient synthesis method for complex multiband specifications.
The paper proposes a novel analytical approach for synthesizing multiband filters that achieves the lowest possible degree filters with given specifications, including multiple pass/stop bands and narrow transition bands. Comparisons show it outperforms existing methods.
A novel analytical approach to the synthesis of electrical (e.g. analogue, digital or microwave) filters is proposed. This approach allows to obtain lowest possible degree filters with given involved specification including e.g. many pass and stop bands, narrow transition bands, high attenuation at the stop bands and low magnitude oscillations at the pass bands. Comparison to other existing approaches is given.
