Scientific and professional achievements
Electrical filters were Mrs. Milić's early field of interest. She focused on computer applications to filter design, and in cooperation with Umberto Kamšek introduced computer-aided design as a method for filter design in the Pupin Institute. Several years of Mrs. Milić's research work were devoted to the sensitivity and tolerances of electrical filters. The results achieved by her studies in sensitivity and tolerances contributed substantially to the quality of numerous practical realizations at the Pupin Institute. In early eighties she started to deal with radio spectrum monitoring and headed the development of real time spectrum analyzer in cooperation with Umberto Kamšek, Marjan Djurić and Anka Kabović. Their contribution to this field was awarded by the Belgrade's Radiotelevision Annual Prize. Since the beginning of 70's, she has developed, individually or in cooperation, a number of original software packages based on self-research results.
Mrs. Milić was leader of numerous R&D projects for a variety of customers and contributed to the development of work and design methodology. In addition, she gave several practical solutions that went into production. She headed a development project for a US client. Since 1976 she has headed projects of the Ministry of Science and Technology. She took part in EU's COST, FP, and Horizon 2020 Programs.
In the field of sensitivity and tolerances, she proposed new solutions for the design of LC passive, RC active and digital filters, which minimize the effects of tolerances in components (or finite word-length effects) on the filter characteristics. With Prof. Jacques Neirynck, she introduced the concept of Equal Ripple Tolerance Characteristic establishing the standard for the best transfer function. She also demonstrated that the effects of losses in components can be analyzed using the sensitivity theory.
In vthe domain of real-time analysis of radio signals, she proposed with coauthors U. Kamšek, M. Djurić and A. Kabović a new solution for the optimal multichannel analog filter bank, and developed a new method for the analysis of the effect of tolerances in a multichannel filter bank.
In cooperation with Prof. Miroslav Lutovac, she has investigated the efficient implementations of digital filters, particularly multiplierless solutions. They introduced the new class of IIR digital filters entitled EMQF (Elliptic Minimal Q-Factors) digital filters, which are suitable for high-speed and low-power consumption systems. In their publications, it was shown that structures based on connections of all-pass sub-filters offer efficient and low-sensitivity solutions in many applications.
Her interest was focused on the design of variable digital filters, on multirate digital signal processing, and on frequency-response masking filters. In cooperation with Prof. Tapio Saramäki, she developed a new efficient method for the frequency transformation for IIR digital filters, and also for the three classes of complementary IIR filter pairs. Applying efficient IIR digital filters based on all-pass sub-filters and EMQF transfer functions, she developed in cooperation with Prof. Miroslav Lutovac and with Prof. Jelena Ćertić several efficient implementations for sampling-rate conversion systems, and also developed several solutions for filters and two-channel filter banks using the frequency response masking technique. The new filtering techniques provide sharp filters and filter banks, thus improving the use of frequency spectrum. She proposed some new implementations for tree-structure multichannel filter banks.
