Abstract: An efficient digital notch filter for 50Hz noise eliminated from low frequency photoacoustic gas sensing signal is presented in this paper by a Matlab program. The digital notch filter is ...

MATLAB-based implementation combining 50Hz notch filtering and statistical analysis for enhanced cardiac diagnostics, as published in our April 2025 arXiv paper.

Abstract: In view of the mechanical resonance existing in electric servo mechanisms, which affects the system bandwidth and steady-state accuracy, a dual-T notch filter with adjustable depth and width ...
