Two single-channel power amplifier modules were designed and manufactured, along with a stereophonic module serving as the basic source of modulated signals. Additionally, measurements were conducted on the fundamental parameters of the completed amplifier, such as harmonic distortion level, dynamic range, and output power. The developed platform serves as a foundation for modifications and further advancement in the technology of building switching-mode audio amplifiers.}, type={Article}, title={Switching-mode audio amplifier based on a ΔΣ A/D converter}, URL={http://journals.pan.pl/Content/131786/5-4584-Jab%C5%82onski-sk.pdf}, doi={10.24425/ijet.2024.149545}, keywords={Acoustic amplifier, Switching-mode amplifier, Digital amplifier, ΔΣ modulation, Class D}, }
