  • The harmonic distortion of the double side band (DSB) algorithm for the audio directional loudspeaker is investigated. The research results show that the harmonic distortion of the DSB algorithm is only influenced by the modulation factor, and is not related to either the modulation signal frequency or the carrier signal frequency. An effective way to obtain a lower harmonic distortion reduce the modulation factor, but it will also result in a lower output signal power. It is necessary and significant for the DSB algorithm to reduce the harmonic distortion and compensate its 12 dB frequency response slope per octave simultaneously.

Abstract: The harmonic distortion of the double side band (DSB) algorithm for the audio directional loudspeaker is investigated. The research results show that the harmonic distortion of the DSB algorithm is only influenced by the modulation factor, and is not related to either the modulation signal frequency or the carrier signal frequency. An effective way to obtain a lower harmonic distortion reduce the modulation factor, but it will also result in a lower output signal power. It is necessary and significant for the DSB algorithm to reduce the harmonic distortion and compensate its 12 dB frequency response slope per octave simultaneously.
