One of the most commonly used non-invasive methods for assessing human exposure to pollution is the analysis of human milk.Human milk analyses help estimate the exposure of infants[1].This is why breast milk is receives scientific interest,and various methods for determining different pollutants from the environment are being developed[2,3].

Comb-Based Filter Design Using Sharpening Technique and Certain Palindromic Polynomial

引用

Journal of Applied Mathematics and Physics 2023年第11期11卷 3773-3781页

作者： gordana jovanovic Dolecek Department of Electronics Institute INAOE Puebla Mexico

This paper presents a novel approach to improve aliasing rejection in comb-based decimation filters. The method is established on certain palindromic polynomials with all zeros on the unit circle and the sharpening technique. As a result, aliasing rejection and the passband characteristic are improved. The method is illustrated with various examples and compared with the methods from the literature. .

Multiplierless Wideband and Narrowband CIC Compensator for SDR Application

引用

International Journal of Communications, Network and System Sciences 2017年第8期10卷 19-26页

作者： gordana jovanovic Dolecek Department of Electronics Institute INAOE Puebla Mexico

This paper presents multiplierless CIC compensator for software-defined radio (SDR) application. The compensator is composed of two simple filters with sinewave form of magnitude responses. The parameters of the design are the sinewave amplitudes expressed as powers-of-two and estimated in a way to fulfill the absolute value of the maximum passband deviation of 0.25 dB and 0.05 dB, for the wideband and narrowband compensations, respectively. The proposed compensator requires maximum nine adders. The comparisons with the methods proposed in literature show the benefits of the proposed compensator.

Design of Two-Stage Comb-Based Decimation Filter with High Aliasing Rejection and Low Passband Droop

Design of Two-Stage Comb-Based Decimation Filter with High A...

作者： gordana jovanovic Dolecek Department of Electronics Institute INAOE

This paper presents a simple method for the design of comb-based decimation filter with a high aliasing rejection and low passband droop. The method is based on the application of the mathematical result on zeros of symmetric polynomials on the unit circle. The application of this result leads to the introduction of the four additional single zeros into comb folding bands, where aliasing occur. As a result, the folding bands become wider and the aliasing rejection is increased. The passband droop is compensated by a simple compensator who works at low rate. The comparisons with the most recent methods from literature confirmed the advantages of this proposal regarding magnitude responses and the required complexity.
