Within a class-D amplifier driving a speaker, which consequence results when the MOSFET switching frequency nears the speaker's resonant frequency?

💡 Explanation

Increased harmonic distortion occurs because decreased impedance near the resonance frequency dramatically alters the gain via the MOSFET's parasitic capacitance; therefore, the harmonic components expand, introducing nonlinear behavior, rather than reducing EMI, improving transient response or stabilizing the power supply.
