Conclusion
Withtheintegrationofartificialintelligence,significantreductionsinTotalHarmonicDistortion(THD)wereobservedacrossvariousfrequencies.Forinstance,atafundamentalfrequencyof72Hz,THDdecreasedfrom49.10%withoutAIto35.22%withAI.Similarimprovementswereevidentat73Hz(THDreducedfrom49.16%to38.23%),74Hz(THDreducedfrom48.43%to41.29%),and75Hz(THDreducedfrom48%to43.09%).ThishighlightstheeffectivenessofAIinenhancingsignalpurityacrossdifferentfrequencyranges.Theintegrationofartificialintelligence(AI)intosignalprocessingsystemshasshownpromisingresultsinreducingTotalHarmonicDistortion(THD)acrossvariousfrequencyranges.Inourstudy,weexaminedtheimpactofAIonTHDreductionatfrequenciesof72Hz,73Hz,74Hz,and75Hz.
Atafundamentalfrequencyof72Hz,theTHDdecreasedfrom49.10%withoutAIto35.22%withAI.ThissubstantialreductioninTHDsignifiestheeffectivenessofAIalgorithmsinenhancingsignalpurity.Similarly,at73Hz,theTHDdecreasedfrom49.16%to38.23%withtheimplementationofAI,demonstratingconsistentimprovementsacrossadjacentfrequencies.
