    Non-linear distortion generally occurs due to presence of non-linearity in the transfer characteristics of transistor.

    If a large amplitude signal is applied to an amplifier in order to extend the operation of a device beyond the linear operational range, then it also generates the non-linear or harmonic distortion.

    As the negative feedback is introduced, the effective input to an amplifier gets reduced which ultimately assists
    it to operate in the linear region.

    This ability of negative feedback proves to be quite beneficial in minimizing or reducing the level of non-linear distortion.
