  • Characterization of radiated EMI generated by digital wireless speaker
    It's worth noting that because radiated EMI is influenced by cable direction and cable length, antenna direction and length should be controlled strictly to reduce systematic uncertainty, when RF current parameter approach is adopted. N. CONCLUSION In the paper, digital wireless speaker is divided into 3*5 units.
